We had a really good time at Fabrizios accomodation. It is very near to the Metro so you can get to the city center in less than 8 minutes. Also, the metro is much more reliable than the bus which saved us a lot of trouble.
The room was clean and just like it was described. We did not use the shared kitchen but there was also a fridge in which every room had its own part. The rooms are a bit noisy. One can hear the neighbors in the adjoining room, but everyone was very considerate.
