My family of 4 (two young children, 3 yo and 5 months) spent 4 nights in the apartment.
Pros:
-Very suitable for small children, including a room with bunk beds, travel crib and toys.
-Audrey was a wonderful host, booked private car transfers between airport and apartment for me. Promptly responded to all questions and requests.
-Apartment location - 15-20 min walk to Vatican. 5 min to Metro station. 2 grocery stores, many restaurants, shops all within a 2-10 minute walk from the apt.
-Apartment itself is clean, comfortable and spacious.

Con - only one
- Hot water, as mentioned by other reviewers, in the bathroom with bathtub was sporadic at best. (However had ample hot water in kitchen and bathroom with shower.)

Overall would highly recommend Audrey and the apartment as the pros far outweigh the cons.
