We were 4 adults who stayed at the apartment for 3 nights and explored Rome for the first time.
We had a comfortable stay. The location is excellent, being 10 min walk from Vatican City and there is a bus and tram stop right outside the door to get into central Rome. It is quiet at night which was good for us. There are supermarkets and restaurants within easy walking distance.
The apartment is on the 3rd floor however there is lift access.
Would recommend a stay at this apartment.
