This is the perfect place to stay in Trastevere, Rome's slightly Bohemian neighborhood that is the home to hundreds of wonderful restaurants. Fab's apartment is small, but it's very nicely furnished and has what appears to be a brand-new bathroom. And Fab is a wonderful host, happy to reserve taxis, recommend restaurants, etc. etc. He responded quickly to all of our questions and requests, usually within a few seconds of receiving them.
Trastevere is a bustling neighborhood in which noise can often continue late into the night. But although Fab's apartment is on a busy (and adorable) small street and close to outdoor restaurants, the apartment faces away from the street and is very quiet.
There is a flight of 19 steps from the front door to the apartment, so you'll be happy you got everything into your carry-on luggage!
