We were really happy with this stay. For some reason I had the impression that it was a private kitchen as well as room/bathroom, but the kitchen was shared. The hosts were very responsive and helpful, the room was great, and the location is absolutely amazing, very quiet and safe, right next to the grocery store, and very close to the vatican. We walked by the bascilica every night to go back.
We brought our toddler, and that worked well, they did have a porta-crib, but I didn't realize you had to let them know about it ahead of time, maybe I did not read the description well enough.
