We had a good stay at Maria's place. They let us check in early, which was great as we wanted to drop our stuff and go out. The two rooms and kitchen had everything we needed, including lots of snacks they left. Maria lives in the same building so that's helpful if needed.
The location is great, lots of cafes, grocery stores and restaurants nearby. The Metro stop Cipro is also a few mins walk and the Vatican is about 15 mins walk so we went twice. The center is also about 20-25 mins away by metro so good to stay in a quieter area with family.
