Sophie was a very nice host, even though I had to wait a bit at the check in, since I came 10 min earlier and I wasn't able to inform her about it, due to the issues with mobile internet connection in the building. The apartment is huge and quite clean. WiFi connection was great and stable, which is necessary for me. Some neighbours were a bit loud during the evenings and mornings, but it wasn't actually bothered me. The location is very good too. If you are coming from FCO airport by train, Termini railway station is 10-15 min walk from the apartment. The metro station is just behind the corner. And some major sightseings (like Colosseum, Piazza Venezia etc) are in 10-20 min walking distance. I hope to stay in this apartment again while I'm in Rome!
