This flat is located in a quiet(er) part of Barcelona, but it is conveniently close to all public transportation -- train, bus, metro. If probably takes 15 minutes to reach the city center via metro. There is a grocery store on the same block, and the building is very quiet! The balcony is exquisite, with great views and private comfortable seating. The washer/drier works well, and there were lots of practical items available for use (fan, lighter, screwdrivers, umbrella, guidebooks, etc.). The stairs to the apartment are steep and plentiful, so don't stay here if you can't climb 70+ stairs a few times per day! Lots of great restaurants around, and the hosts have provided a nice list of their recommended places. Reliable wifi.
Alfons checked in with us periodically to make sure things were going well, which we appreciated. He was very kind! Overall, the apartment was clean and well-supplied -- a great home-base for exploring Barcelona!
