Ana was a very helpful host. On request she has provided us with additional useful information about BCN, places to visit, where to eat, online tickets, storage places, etc. The apartment itself is comfy and cozy. We were traveling with a little kid and there were two things uneasy to be in this apartment because of that: the floor that is really making a lot a lot of noise (sleeping baby and this floor was somehow a problem) and second thing: very thin walls to the neighbours (we could hear them talking, etc so I believe they heard our baby too.
The shower is very tiny and there is almost no way not to spill the water on the floor. The bed could be more comfy.
Summing up, nice apartment, good location (great food market just outside of the apartment), helpful host.
