The appartment is well located, central (inside the walls) so easy to visit the historical sites (metro and tram very close but also accessible by foot), and in the same a bit further from the very touristic center, so better to find better food for cheaper...
I didn't realize when I booked that it is not the house where andrea is living but an appartment to be shared with other visitors (3 bedrooms), anyway the appartment is convenient, the 3 rooms have their own key and the kitchen and bathroom to share, appartment well equiped. As I was the only one in february, I had the appartment for myself!
I didn't really see andrea (just twice very fast) but he was very easy to contact and he answered promptly to all my questions, so I knew that he would be there in case of any problem
The little thing to notice is that the appartment is very dark as it is located half underground, that means also very bad connexion for telephone (however wifi is very good), but I didn't really care as I was in Rome to visit and enjoy to be outside...
