Highly recommended!

Really enjoyed my stay at the hotel. It's located in the nicest part of Bracelona, along the Diagonal Avenue. It's useful that the hotel is situated right next to the beautiful L'illa Shopping Centre (the mall's food court had an impressive variety of culinary options). Rooms are large and nicely decorated. Hotel staff are overall polite, professional and very helpful. There is special attention to cleanliness. Breakfast was nice, although the variety of the main courses could be improved. Again, the waiters were efficient and friendly. Would definitely want to go again.

Very pleased with our room. It's spacious. Modern design, it's exactly what we're looking for. Price reasonable. Location close to malls. Just a bit disappointed when we asked for house keeping. I saw spots in the bathrooms which shows it's not seriously cleaned. Hairs.were still on the floor. Overall, we're happy with our stay. Highly recommended
