Location! It's perfect for people, who really want to enjoy La Rambla night life and morning breakfast at Boqueria market at the same time. Metro station Liceu is very close (3-5 minutes, walking distance). At nights, it is a little bit noisy outside. Well, "thanks to" night life. However, there are no night clubs/bars in the buildings around. So, not so much noisy as it could be in the center of Barcelona.
Gianluca is great host, easy to reach and quick in responses. He recommended us some places to eat in the city. Easy check-in.
It was nice to stay in his apartment!
