We had a great stay at Mary's! It was very clean and a beautiful apartment. It was a tiny bit small for a group of 4 adults but it worked fine for us and it's perfect for families traveling with two younger children. The area is beautiful and safe (Vatican. Wall across the street) but a bit of a walk to get get to the metro (10 mins). If you're looking for peace and quiet and don't mind a bit more effort to see the sites, then this place is perfect. The WiFi tends to be slower during the day which can be an issue if you're trying to research bus schedules/book tickets. Overall, we had a great stay and Mary and her staff were very attentive and understanding of our needs. Thank you!
