Salvatore and Nicoletta were great hosts. Salvatore was very responsive. I was here for 5 nights in one week and another two nights the week after, using two separate rooms in the same flat. Only thing I'd like to note is a negative as well as a positive to this place and it is the location. Firstly, it is close to the termini station, which helps when you are travelling by metro/bus/train. However, it is also a very popular area. There are constructions going on and in our first and second day there was no electricity. The location is heavily/easily influenced and affected by the surrounding. So just be on your guard for that.
Other than that, I feel it was rather pleasant :) Many tasty restaurants nearby too.
