Massimo's apartment is great - very clean, very modern, well decorated and located in a very alive and nice neighborhood. The neighborhood was a great finding in the expensive Rome as it was cheaper than anywhere else. And it really felt good to pay 2,60€ instead of 6€ for a beer! The apartment is very close to a variety of bars and restaurants (we tried some and we were not disappointed with any of them!)
We stayed 3 nights and we felt "part" of the neighborhood since the first night with the friendliness of the ambiance and the people.
The only problem is really the noise until at least 3 a.m. in any day of the week, due to the bars in the same street.
Massimo's was a great host, received us with a lot of sympathy and was always available when needed.
We missed a bread knife in the kitchen though ;-)
