  We loved this hotel. We had a large room very comfortable. Staff were very nice. Nice outside deck are and common space. Not the most ideal location to attractions but in a nice business area.

  SAFETY WARNING: Life-Threatening Incident and Zero Management Accountability

  08 Jan 2026

  I stayed at this property from November 26th to December 18th, 2025. While I am a loyal Marriott Gold Elite member, I feel it is my duty to warn other travelers about the serious safety risks and the lack of professional responsibility at this hotel.During my stay, I suffered a life-threatening incident caused by gross negligence within the property. I have clear video evidence of this event, which proves how dangerous the situation was.The most shocking part was not just the incident itself, but the management's reaction. I reached out to the General Manager, Mr. Ruiz, multiple times to find a fair resolution. Instead of taking responsibility for a guest’s safety, the management chose to ignore my emails for weeks and eventually hid behind vague corporate excuses.If you value your safety and expect a professional response when something goes dangerously wrong, I strongly advise you to look elsewhere in Barcelona. A brand like AC/Marriott should prioritize human life over bureaucracy, but unfortunately, that was not my experience here.The matter is now being handled by my legal counsel. I have all the documentation and video recordings to support these claims.Stay away if you expect a safe environment and accountable management. Alejandro R, at Ac Hotel Diagonal L"illa, responded to this review Dear Mesut Firatoglu,We sincerely regret that your experience did not meet your expectations and are sorry for the discomfort you describe. The safety and well-being of our guests are an absolute priority for AC Hotels by Marriott.Following the incident to which you refer, the hotel team acted in accordance with the established internal protocols, making all reasonable efforts to ensure that your stay could proceed under the best possible conditions and that you were able to enjoy the services contracted, as indeed occurred. The hotel strictly and continuously complies with all applicable safety regulations and carries out periodic technical inspections of its facilities in accordance with the brand’s operational and safety standards.We carefully consider our guests feedback and use it as a basis for implementing measures aimed at the continuous improvement of the guest experience. In this regard, we take note of your observations as part of that ongoing commitment.As you have indicated that this matter is currently being handled by your legal counsel, and out of respect for the ongoing process, as well as in accordance with the company’s corporate policies, we are unable to provide further comments in a public forum. Any subsequent communication should be conducted through the appropriate legal representatives.Sincerely,Alejandro RuizGM

  Stay was great. Location is v good. Boring Breakfast

  28 Dec 2025

  Stay was great. Location is v good. -->Right in front of bus stop, next to a mall with grocery store and medical shop.-->Room sizes are the best part about the hotel.-->Staff was very accommodating, special mention for ISI from the Front Desk and Patricia in the restaurant. V Helpful.-->Daily housekeeping was an added advantage.-->Breakfast is very very boring. I mean its exact same every morning, just 1 change of dish else exactly the same what they serve daily. There could be so many options to be on rotation. For a brand like Marriott, this is something they really need to fix. -->Disposable Glasses in rooms instead of crockery feels so low grade hotel.-->More and properly placed switch board in the room would be helpful.I would recommend the hotel for a stay in Barcelona.

  Long check out junior staff

  12 Nov 2025

  The hotel is in a business area, rooms are nice. Anyhow it seems that the staff is extremely junior and not familiar with the system. They messed up with the deposit and at checkout out they were not able to release the deposit so I had to pay again blocking my card for the double of the amount.., the long and messy check out caused me to loose my train. They denied any responsibility once they caused issues. Usually in customer service the starting point is to say sorry … in short nice hotel but staff junior and not professional, for sure not up to the price and hotel category. Alejandro Ruiz Roig, General Manager at Ac Hotel Diagonal L"illa, responded to this review Good morning Mrs. Giani,We truly appreciate your email and feedback.As mentioned in our previous communications, we have repeatedly apologized for any inconvenience this situation may have caused during your trip.After consulting the matter with our Leadership Team, we genuinely believe that the loss of your train was not our responsibility, as you came down to the Front Desk for check-out only 25 minutes before your train’s departure.Once again, we sincerely apologize for any inconvenience caused, and please do not hesitate to contact us again, we would be delighted to welcome you back on your next visit to Barcelona.Kind regards,AndreaReservations DepartmentAC Hotel Diagonal L’Illa by Marriott
