We stayed at Pau's place for one month. The apertment is cute in an "original" building from BCN. It is clean, comfortable and very silent at night.
There was everything we needed, plus toys for the kids.
Pau also increased the speed of Internet so my husband could work from home.
Only thing we didn't liked so much so much it's the barrio itself, since it seems is going into a big renovation, so there are worksite everywhere. But it's true that walking for ten minutes you find everything you want or you can catch a metro/bus/tram.
The elevator is really cute, and we could fit our strolley that has a normal shape (Valco Baby 3).
