This place saved me as I was supposed to stay with a friend but something came up and I had to find accommodation on the run.
Let's start with the obvious: if you're looking for something to be in walking distance from the attractions, this is not the place. It's pretty far from the tourist sites, but there's a tram close by and also the Trastevere train station (which was very handy for me). The price is really good for Rome and the area is quite and safe.
The room was not exactly my taste. Very crowded, old furniture, a little dark because of all the stuff. On the plus side it had a private bathroom (which was also pretty old school).
Both room and bathroom were clean but because of the stains on the walls and the old look it didn't always feel that way.
WIFI was present but at full signal it could barely load a video.
Summed up: an economic and private place away from the agitation of touristic Rome.
