Really enjoyed our 11 nights at this hotel. The bed was incredibly comfortable, and the room was spacious. We also had views of the Sagrada Familia, if you ducked your head and turned right. We only did the breakfast for 3 days, but for only 10 euro (you have to tell them before to get that rate), it was a pretty solid spread.
We did have issues finding a good place to work early in the morning that wasn't the room. They have a communal space on the ground level, but it doesn't open until 7-7.30am. Also the gym is pretty much a room with a few weights and one eliptical machine. Better than no gym at all, don't get me wrong, but not really a gym.
Overall, great stay at the hotel, would go back again for the bed. The housekeeping was also top notch!
