We had a great stay in Trastevere. The room was ok, we had a lot of privacy, but it is really bright in the morning (no curtains). We met Federico only in the checkin, most of the time we were with Gabriel, who is a nice guy and helped us with some things, but didn't speak English. (But he really tried to communicate! I appreciate that). Trastevere is a really great neighborhood and we liked a lot staying there, the house is in a quiet street but if you walk a bit you get in a very nice nightlife.
