H15 Boutique Hotel, Warsaw, a Member of Design Hotels

Dining: The breakfast is described as authentic and chic, with a good variety, although not as diverse as global chains. The on-site restaurant receives high marks for its exceptional service and food quality, contributing to memorable dining experiences.(based on 1 review)

We loved the historic building of the H15 Boutique Hotel—it’s fascinating to imagine its past as the Soviet Embassy. The location is fantastic, with plenty of restaurants nearby, and we even walked 30 minutes to the park for the free outdoor Chopin concert. We stayed in the Luxury Suite. Oddly, the hotel doesn’t list a balcony, but we expected one based on the photos. The suite itself is spacious, with a huge living room and bedroom, though the bathroom feels small by comparison and has limited counter space. Breakfast is overpriced and mediocre, so I’d recommend eating elsewhere. Overall, though, I’d definitely recommend the hotel.

My name is Roberto Moretti, Ambassador Bonvoy member and Platinum Lifestyle with over 900 hotel nights. I booked this hotel for 3 nights from November 19th to 22nd, 2025, and I booked their presidential suite. For sure One of the worst hotels I've ever seen. The service is terrible, embarrassingly unprofessional. The management is shameful. The conditions of the room when I arrived were disgusting, it felt like I was in a run-down 3-star hotel. 1 - window broken and left open with the bedroom temperature around 14 degrees. 2 - power outlet detached from the wall, with silicone outside and electricity that came intermittently causing sparks between the wires (absolutely third world). 3- The technician who fixed the broken things, finishing at 8pm, left pieces of sheet metal on the floor in the room. Everything is documented in the photos. Finally I get the room at 9 pm 4 - Both smart tv are not working I then asked to change rooms and the response was: we don't have another room in this category, this is our best; I then asked to speak to a manager and the response was: There is no manager, the first one can contact you tomorrow... I then specified that I wanted to be met at 2.30 pm in my room. To my great surprise, the next day the manager didn't show up for the appointment, he didn't warn me or call me, in short he didn't give a damn. At check-in (carried out by a gentleman in training), they didn't even mention that I was a Bonvoy member. This hotel is completely outside of Marriott standards, outside of international 5-star standards, and is a completely run-down establishment. The general manager, Mr. Jacek Suchenek, is completely incapable of managing it or maintaining its standards. I just want as many travelers as possible to stay away from this establishment, which, aside from the fake awards, is run-down, non-luxury, and completely lacking in service. I hope that Marriott removes this structure, the incompetents who work there. I hope that after opening a complaint about the safety of the electrical socket and reporting it to the Ministry of Tourism and the embassy, ​​they considering the absolute non-compliance with the standards of a 5-star hotel, the ministry will send inspectors to downgrade it to its original level. Stay away and don't let your money get stolen here. The only real 5-star hotel in Warsaw is unfortunately the Raffles.
