We loved this apartment! Francesca's mom met us at the apartment and had baked us a cake to welcome us! We were blown away by the thoughtfulness! It is in a really amazing location... We loved Trastevere. We used taxis most of the time to get into rome city center and to the Vatican city so I can't really speak to public transportation from Trastevere. There is a restaurant attached to the building, one across the street (which plays music through the evening that you can hear from the apartment... Such a fun environment!) and another on the square to the front of the building. I would definitely recommend this apartment.
