The apartment is very nice, very spacious and the location couldn't be better. It is a couple blocks away from the Coliseum. There are plenty of restaurants right outside and around the building and a metro station one block away. You can walk everywhere and if you don't want to walk the metro is right there and the main train station is 2 minutes away. The apartment is very quiet, no street noise.
Paola was very accommodating with the check in time and check out time. She also gave us some suggestions about restaurants and the best way to get to know the city. We had a great time in Rome and I can't think of a better location.
