Great! I had a very plesant stay at carla's flat. Carla and Imma where very nice and they welcomed me very well.
The apartment is spacious, very clean, modern. Exactly like is the photos.
True it's a bit dark because of it's configuration, but it didn't bother me at all.
Location is great to visit the city, you can go by foot or take the metro near by. So i would recommand this place.
