We had a warm welcoming, the reactiveness is good and we were given great addresses for visiting, eating...
The apartment is at the 3rd floor (with no elevator but hey, it's a little exercice to make the tapas disappear from your body !) it is clean and well situated (Near Poble Sec metro station).
There's also fans in almost every room, and THAT is very useful !
A supermarket is next to the entrance of the building.
I recomand this apartment !
