No complaints for us in this very enjoyable stay. Communication was always 10/10, the rooms and bathrooms were spotless.
Great for two people on a longer stay, especially if you enjoy walking: there are bus stops very close by if you don't, but many other interest points are accessible via 15-20 minutes of walking. Sagrada Familia 10 minutes away. Supermarkets available all around.
The builiding is old and has thin walls, but the other residents were very respectful and quiet, we had no trouble sleeping. We liked seeing the architecture from inside and outside.
