I really loved this apartment - it is full of light and a really nice space to spend time in. Three of us stayed (one couple and a single) and there was plenty of space for us. I loved the area, found it easy to get around Barcelona from there and could easily walk to La Sagrada Familia, Casa Mila, etc. I thought it was a bit odd at first that the apartment is owned by a hotel, but the check in process was smooth and they were really lovely and helpful - it didn't really feel different to my usual Airbnb experiences with private home owners.
I would recommend this place!
