Giusi was nice and answered really quickly. The location of the apartment is really good, especially if you are looking for the nightlife of Trastevere! Still it's relatively quiet inside the apartment and you can get a good night sleep. It is a bit dark there, practically no daylight inside. Also the flat is a little worn out, the kitchen and the bathrooms have seen better days.
A good flat for young people to party and enjoy Roman nightlife. Maybe not the best option for families with children.
