Apartments are clean and cosy and are situated relatively close to Vatican. The owner is a pleasant person who gave us all necessary information and left for us a bottle of water and wine. There is a supermarket just near the apartments, and a cafe which works 24 hours and where you can order tasty coffee. Gelateria is also very nice.
The only thing that troubled us a lot was non-stop traffic noise, but Rome is a very noisy city in general.
