We really enjoyed our stay in Alessandra's apartment. When we made the reservation I made a mistake with the dates by chosing too long a period: Alessandra immediately offered to modify the reservation so I wouldn't have to pay the extra day, which I found very generous. Then during our stay she was always available to answer questions by mail, and work through any little problem we might have. She wasn't there when we came so we didn't get to meet in person but by being so friendly and available she really helped make our stay enjoyable.
The apartment itself is very comfortable, there is a vintage style for all the furniture and decoration that gives it a peculiar charm. Everything worked perfectly. You should know that the apartment isn't very far up (it's maybe half a floor above the road) but that wasn't a problem, it's still quite luminous and intimate.
The best thing about the apartment is its location, it is between the Vatican and the Castle Saint Angelo, really perfect for visiting the city.
All in all a great experience with wonderful hosts who did everything they could to help us enjoy our stay.
