This apartment is in a fabulous central location. It took us 5 minutes to walk to the vatican and only 20 minutes on the metro to get to the Coliseum and all of those attractions nearby. You can literally walk to all of the spots that you want to see.
Lovely restaurants are on the street below and Cristbel recommended a great pizza place two blocks up. We also went to one called Blanche just underneath the apartment building - the food was excellent but more expensive than the other places around it.
The apartment itself has huge bedrooms and a great sized kitchen and living space. It is modern, clean, well cleaned and has everything that you would need. 4 of us stayed there together very comfortably and Cristobel was not intrusive at all and was thoroughly prompt and helpful; making some good suggestions for our stay!
Honestly, if you book to stay here, you can only be pleasantly surprised. The pictures and description do not do the apartment justice. After this stay, I am an AirBnB convert!
