Location - It's close to Trastevere, not necessarily smack dab in the middle of the more happening part of town. You'd need to walk 20minutes to get there.
Transportation - buses and trams are minutes away.
Space-We were three people in this apartment.One of us had to sleep on the couch which was fine. Francesca informed us about that beforehand.
Host - Francesca was a helpful host. Her son welcomed us on our first day and was also very available if we had any questions.
