Location, location, location! So close to the Vatican yet a quiet building. Felt very safe, even at night. We had an issue with the shower not draining and some lights not working, and Piero had someone come first thing the following morning after I notified him. The washing machine/dryer combination was a challenge to use. The shower water temperature changes a lot, so be prepared. There is only one set of keys, so that posed a few issues a couple of times.
I would recommend staying here!
