The apartment is exactly as described and was immaculate throughout.
The outside terrace is a real bonus, particularly in the warmer months.
It is located in a very quiet area (always remembering you are in Rome!), and only a few minute walk to the Metro. We used public transport throughout our stay and never waited mote than a few minutes. I would recommend investing in a Roma pass if you are doing a lot of travelling and visiting museums etc, otherwise just buy a bunch of tickets from any newspaper kiosk (1.5 Euro each for 100 minutes of travel on bus, tram or metro).
If you get the chance go to Ristorante Alfredo!
