  Good choice in Marais

  26 May 2026

  We spent one night at this well located hotel in Marais. I did very little research other than a quick google search as we were walking around Paris so was delighted that we had a very nice executive room that was spacious, comfortable and had nice amenities. The room was clean but I still always wipe down things. We probably weren’t there long enough to really appreciate the room or the property so the price felt a little steep but such is real estate in Paris. Responsable Relation Client, Propriétaire at Experimental Marais, responded to this review Dear Guest,Thank you for sharing your feedback following your recent stay.We are pleased to learn that you enjoyed the comfort and spaciousness of your executive room, as well as the amenities provided. Your satisfaction is truly rewarding for us.We hope to have the pleasure of welcoming you again soon for a longer Parisian experience.L'équipe Experimental Marais

  Review of Experimental Marais (formerly The Sinner)

  17 Feb 2026

  I am currently staying at Experimental Marais in Paris, formerly known as The Sinner, and I feel compelled to share honest feedback about how dramatically the experience has changed since the rebranding.When it operated as The Sinner, the hotel had a strong identity. It paid attention to detail. It had character, atmosphere, and a sense of theatre. Today, while the price has increased, the quality of service and overall experience has noticeably declined.The concept that once made this hotel distinctive now feels diluted. It has become another expensive boutique hotel, but without the soul that once justified the rate. You pay more, yet receive less value.With the new branding , they took away the air fluffed extra duvet, added bulky room key, and made it more towards dad and mom are going to send a night at an expensive boutique hotel!Cleanliness & Maintenance ConcernsThere are several issues that should not exist at this price point:Mug rings were left on the bedside tables upon arrival.The bathroom tissue box was EMPTY. The house slippers were too small for a man's feet, and when i asked for a bigger size , they staff member told me thats the only size. but the following day when i asked about a bigger size, it was magically searched and found , then delivered.The coffee table was not properly cleaned.The rug did not appear freshly vacuumed.The bed linen had a strong detergent smell that was unpleasant rather than luxurious.In Room 205, the paint is peeling from the shower ceiling.These are basic maintenance matters that undermine the perception of a luxury property.When I arrived, the AC in my room was not functioning and could not be repaired until the following day. My only temporary option was to use Room 101, the accessible room for guests with disabilities. I was uncomfortable taking that room, as it should be available for someone who genuinely needs it. Meanwhile, my own room had a noticeable vanilla and tobacco odor, and during the afternoon there were also kitchen smells drifting into the room. Without working air circulation, these odors lingered and became more pronounced. I was advised to open the window, which is not something one expects to hear in a hotel that positions itself as luxury.Dyson Hair Dryer ExperienceThere is now a standard hair dryer in the bathroom drawer. If you would like a Dyson hair dryer, you must sign a form acknowledging receipt, after which one unit is brought to the room.The staff member who delivered it did not speak English, which made communication difficult and diminished the service experience. More concerning, the accessories of the Dyson contained hair from a previous guest. That immediately raised questions about hygiene standards and attention to detail. I had initially requested both the Dyson hair dryer and the straightener, but after seeing the condition of the attachments, I declined. If the accessories are not cleaned properly between uses, this is a serious oversight.In most five-star hotels, premium hair dryers are simply placed in the room, and guests are charged if they remove them. Requiring a signed form for a hair dryer feels unnecessary and inconsistent with a high-end positioning.Loss of IdentityUnder The Sinner, the hotel had a unique scent and atmosphere. The music outside the rooms differed from the music inside. Staff uniforms were distinctive. The experience felt curated.Now, the music is the same throughout. The signature scent has been toned down or removed. The staff attire no longer conveys a strong identity. The toiletries have changed from something that felt unique to something very common. Even the bathrobes now simply display the hotel name, which feels more commercial than refined.Previously, when you passed the hotel, you didn't know it was The Sinner. There was no presence. Now, it blends into the street. Outdoor seating has been added, yet the surrounding neighborhood is not particularly suited for people watching. It does not enhance the concept.Service & OperationsService has slowed. When I requested plant-based milk, it took a considerable amount of time.The WiFi process was unnecessarily complicated. Even when I called reception, the staff member was unsure whether the password required capital or lowercase letters and asked me to try multiple variations. In Room 101, the phone did not clearly indicate which number to dial for reception.These may seem like small details, but luxury is defined by seamless execution.Positioning & ValueThe hotel promotes environmental messaging with cards encouraging guests to reuse towels. While sustainability is important, when guests are paying premium rates, the emphasis should first be on service and comfort. At this price point, guests come to feel cared for and indulged. The experience should not feel like a standard commercial chain.Today, Experimental Marais feels like an expensive hotel without a distinct reason to choose it. I was initially planning to stay longer, but I will not be extending my stay. The emotional impact and “wow” factor that once defined The Sinner are no longer present.Previously, I would enthusiastically recommend this hotel to friends. Now, I cannot. I could have chosen the InterContinental Paris Le Grand or the Sofitel Le Scribe Paris Opéra, earned loyalty benefits, enjoyed potential upgrades and breakfast privileges, and likely received a more consistent luxury experience.Unfortunately, choosing Experimental Marais after its rebranding feels like a mistake. I sincerely hope management reflects on what made The Sinner special, because at present, the hotel has not only changed its name, it has lost its identity. Responsable Relation Client, Propriétaire at Experimental Marais, responded to this review Dear Sir,Thank you for sharing such a detailed and thoughtful review of your recent stay. We sincerely regret that your experience did not meet your expectations, particularly regarding the service, maintenance, and distinctive identity that initially attracted you to our hotel. I'm sorry to hear that you miss the Sinner concept, but the Sinner no longer exists. You have to let it go.Yours faithfully, Simon SalléHotel Manager

  Cool Location in Paris

  18 Sept 2025

  The hotel is in quiet location in the Marais area of Paris. The concierge and desk staff were very inviting. The room was large and spacious. The lighting set up in the room and figuring out which switch controlled which light was confusing and after a while I gave up.

  Fantastic hotel. Rooms are comfortable and clean. Comfortable bed, helpful staff and amazing location. We especially loved the night staff (we didn’t get their names!) who made us feel at home and took fantastic care of us. There were some staff who felt a bit less professional and warm than the night staff but the night staff were just incredible! Hotel Manager, Owner at Experimental Marais, responded to this review Dear Mia,We appreciate you taking the time to share your experience.It's delightful to hear you enjoyed your stay at Experimental Marais.We're thrilled our central location in Le Marais provided such convenient access to Parisian landmarks, and that you found comfort in our thoughtfully designed rooms. Your recognition of our night team's dedication particularly resonates with our commitment to attentive service.While we regret any inconsistency in service standards, we continually refine our training to ensure every interaction reflects our values.Finally, we're glad our spa facilities and Temple & Chapon restaurant contributed to making your visit memorable. The Roman bath remains a guest favorite for unwinding after city explorations.We look forward to creating more exceptional experiences for you.Warm regards,Lewis MDeputy Hotel Manager

  Not such a good experience

  09 Jul 2025

  Friendly welcome and staff. The problem lies with the layout of the rooms - and the rates:- control and regulation of lighting unnecessarily complicated and impossible to understand- notoriously inadequate lighting, including in the bathroom- badly placed sockets- dangerous step in the bathroom- outrageously expensive at 750 EUR!The restaurant Temple et Chapon is nice. Hotel Manager, Owner at Experimental Marais, responded to this review Dear Guest,Thank you for taking the time to share your feedback with us.We're pleased to read you appreciated the warm welcome from our team.However, we regret your experience didn't fully reflect our standards. Our rooms' design by Tristan Auer prioritizes both aesthetic harmony and functionality. Additionally, our team is always on hand to assist with any concerns, such as lighting adjustment, during your stay. Regarding pricing, our rates reflect the 5-star experience including access to our Roman bath spa and Susanne Kaufmann treatments.Nevertheless, we're delighted you enjoyed Temple & Chapon. Chef Mélanie Serre's New York-inspired menu in our neo-Gothic setting remains a highlight many guests appreciate.We hope that you will choose to revisit us.Best regards,Simon SalléHotel Manager
