We stayed for 4 nights at Cristina's place and really enjoyed our stay. The place was clean, spacious and well equipped. The location is further out from the main attractions but after being in crowds all day we were happy to go back to the quiet neighbourhood. It took max 30 minutes to get to the major attractions (Colosseum, Vatican etc) by taking the tram then metro. You have to pay the cleaning fee and city tax in cash which is a bit weird (prefer to do any payments through the app), but overall we were happy with our stay.
