I was staying for the Primavera festival.
The hotel is in a great location, close to the main street, which has great choice for restaurants and shops to stock up on food for your stay. Metro and tram are within ten minutes and 15 minute walk.
The air conditioning is good. The room was big and the bed was comfortable. Even though you are on a busy street, you will still get a good sleep as the noise is blocked very well by the windows. But it isn't that busy, gets quiet at night.
The staff were really good and helpful, and the rooms were cleaned very well. The bathroom was very nice, good bath, and plenty of towels are provided.
Overall I would say this is one of the best hotels I have stayed in. As you are in the center of the city, close to everything and would definitely consider staying here again if and when I visited Barcelona again.
Great work.
