We stayed at Alessandro's apartment for 4 nights while visiting Rome. The place is 15 mins walk from Vatican and hence very convenient to visit there at your leisure. The place is also less than 10 minutes walk from Ottaviano Metro (A) station and hence very convenient for moving about anywhere in Rome. There are also bus stops within 2-3 minutes walk as well as restaurants and supermarkets within the same distance.
The apartment itself is very clean and tidy with all basic amenities provided. Easily sleeps 4 people. I would recommend strongly this place to couples and small families. The apartment is very secure and checking-in/out is very convenient.
