I stayed here 3 nights, and loved the the location in Trastavere. Maurillio, the host, was very welcoming, and made sure I had everything I needed for a satisfactory visit. The neighborhood was lovely and the room was quiet in the evenings, despite its location adjacent to (and above) a restaurant. Breakfast items were provided as well, although there are several great coffee and pastry shops in the area. Dependable WiFi was available.
There was no lock on the room door, although there was solid security for the apartment.
Staying here felt like being part of the neighborhood. Lovely.
