Ingrid was an wonderful host :-) very, organised and easy to communicate with. She also gave us really great tips for what to do while visiting Rome. Trastevere is an excellent area to stay in, vibrant and full of restaurants and bars, so much to do you almost don't have to leave.
The room in ingrid's apartment is very loud, you hear all the street noise and the noise from the surrounding bars, but a pair of earplugs dulled it enough for us to get some sleep.
Despite the noise we had a very pleasant stay with Ingrid :-) Trastevere is worth a visit.
