We stayed 6 nights at "GiaRia", and this was an excellent base for our Rome trip. Giancarlo was extremely helpful, providing useful restaurant advice and arranging for a transfer to the airport. The place is clean, comfortable and had everything we needed and more. The bed was very comfortable and we had instant hot water for shower. Slight noise filtered in from the street even though the apartment is facing away from it overlooking a small courtyard, but this hardly bothered us and considering this is Rome I am sure this place is probably one of the quieter options available. The location is very good - easy access to sights on foot or by public transit, whichever is your preference (we tried both).
All in all I highly recommend Giancarlo's place - for an unbeatable value.
Mille grazie!
