We would definetely recommend staying in Edoardo's appartment. We were received by Edoardo's mother, who was very friendly and showed us the appartment.
The description of the appartment was very accurate, and the appartment looked very much like the pictures. It is not a very large appartement, but it has everything you need and a good atmosphere.
Although the location is very good (near several bus and metro stations), the neighbourhood could have been better, especially the area around Termini station.
