Mauro is a very friendly host, he always answer your questions very quickly.
The apartment is very convenient to everywhere, it took me only 10 minutes to walk to Sagrada Família. Line 4 and line 5 both have stop near it. The apartment is over 100 years old, and that makes us feel like living in the history. The facility is new, but the hallway is a little narrow.
Anyway, I would like to live in Mauro's apartment again if I go to Barcelona next time.
