This is my first bad review in over 20 countries.
Cleanliness/mold/shower grime and intergrity of showers were an issue (i.e. fixtures staying attatched). There are two bathrooms in the kitchen so be prepared to walk past everyone eating to shower or use the toilet. Towels smelled of mildew and had the texture of sandpaper.
Communication was absent or impolite at best. There was a general consensus among guests that Silvia does not like having guests, at least she was very clear that we were an inconvenience to her. We altered our check in to meet her work schedule and then she announced a manditory check-in within only a 20 minute window between 3pm and 11pm that was actually the same time our train was arriving. Luckily the other guests were there to help. The "host" is not easily reachable in emergencies so get a phone number from another guest. When we needed help, she got back to us the next afternoon saying she asked another guest to help us - no one came.
The only reason we elevated the rating to 2 stars was because there was AC. But be warned that Silvia, while she will not readily respond to emergencies, check in, or concerns, she is quite eager to tell you that you should not be using the AC. We were told twice that we were using it too much in our room as apparently 72 degrees while we are there and 85 while we are out is an egregious overutilization of the advertised amenities during Rome temps around 95 degrees.
There are some good places to eat nearby, and the location is not bad, but plan to arrange your own taxi as Silvia seems to have a record of forgetting to schedule them after saying she will. The most we paid for a taxi was 13 euros to the Vatican, usually 6-8euros to major attractions, cabs to the airport are a flat 48euros. The train station is about 12 - 15 min walk.
General impression: Sylvia seems to be running a 10 room hotel, but is not actually caring for her guests or pride in the establishment - just cashing the checks. There is AC that comes with chastising for use. The small stand up shower is a struggle and has gross walls and fixtures. Be careful as floors are super slippery if damp.
