The apartment is very spacious and comfortable with a big patio where you can sit in the evenings, or eat your breakfast in the mornings. It is also very well located, you can basically walk to most of the touristic places. Since all the windows go out to the patio, the apartment is quiet, which allows you to have a good rest after an intense day in Rome. If you are staying there in the summer you will also appreciate that it is quite cool. The kitchen is very well equipped, there was even coffee and milk when we arrived:) I haven't met Giuseppe in person, but he was very easy to contact and flexible.
I stayed there with 5 other friends for 4 days in the beginning of August and we had a very good time. I definitely recommend this apartment to everybody.
