Mario is a great host. We were welcomed in his appartment by a freshly brewed coffee and received lots of local tips from him. The bedroom and private bathroom were perfectly clean and cozy. The double bed was very comfortable. There are also two friendly (but not intrusive) cats in the appartment.
The locality is very good. We felt safe even in the evening, it is also relatively quiet. The metro station is just around a corner. There is also a great café and a famous pizzeria Starita in the neighbourhood. The city centre is also reachable by foot within about half an hour.
