We had a really nice stay at Oscar y Susana's. They were really nice and gave us good tips about restaurants. The place was clean at our arrival and they even thought about leaving a bottle of Cava for us!.
The apartment is well equipped and the neighborhood is great. Within 3 min walk there is a metro station, a bakery, a grocery store and really nice restaurants on carrer de Blai!
The apartment is perfect for a couple or a family. But I wouldn't recommend for friends because the toilet is inside the main bedroom.

Thank you very much!
