The apartment is in the center of the Monti neibourghood which is lively and beautiful. A lot of things are at walking distance (coliseum, stores, restaurants/bars, trevi, etc.).
A downside of being so lively is that in the evening there was some slight noises from the bars and restaurants but nothing unbearable (especially if you are part of the noise ^^)
To sum up, the location was ideal!

The apartment was clean and has a lot of character. It enhanced our experience in Rome.
Note that one of the best ice cream we had during our stay was in the gelateria next-door ;)

We were welcomed by Barbara's friendly and helpful husband Lucca (and his sister) . He gave us some information and restaurant recommendations.

We had a very good stay in this apartment and will return!
