The place was perfect!
The best thing was the location, the neighbourhood is beautiful and everything is very in reach, especially the Sagrada Familia. A good few shops and restaurants are located very close by as well. The place itself is nicely decorated and very clean. I have a brother with asthma and dust allergies and the place gave us no trouble at all.
The host is also very nice and helpful, they replied to all my messages very quickly and were very accomodating.
Overall we enjoyed our stay, and definitely wouldn't mind coming back :)
