The apartment was clean and it had everything we needed.
Some things we didn't like were the missing door handles to 2 of the doors and the fact that you could hear your neighbors speak and making noise.
Otherwise, excellent location, close to the metro and bus stops, and lots of restaurants and bars nearby (we recommend Yogi Bar, Bar Ara and Bar Ibèrics).
Communication with the hosts was OK, they replied very fast and Niko helped us when we had a problem. Plus, they allowed us to check-in a bit late, which was nice!
I would recommend it, it's a nice apartment for a group of 4-5 friends, comfy, good price, also nice and quiet neighborhood, close to cheap supermarkets (Consum) and bars.
