The flat is really great. Sofia waited for us at home to give us the key and was totally flexible with arrival and departure time.
She left us some pasta and tomato sauce, really nice !
The apartment is in a really quiet area named Testaccio, nearby Trastevere which is more fun.

The apartment is well appointed and well furnished. I just have to tell that it's apparently an apartment dedicated to rental and when we arrived, we found the place not that clean .
Except that, everything was great, thanks Sofia!
