Barcelona city stay

It’s a beautiful modern hotel right at the mall. The public transportation is in front to it & some nearby stations. Internet access is free. Room is clean and spacious. Breakfast buffet is excellent. Even their evening menu is great with a soothing restaurant ambience. The buffet paid inclusive is for 2 people only with family of 4. So we had to pay extra. The staff are really helpful.

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.
