This was a great place to stay! It is essentially a hotel guest room, located in an accessible part of Trastevere, close to trains and bus stops right in front of the door. The host was very responsive and was there for anything you needed. Once a day, if you are out of the room before noon, your room will also be refreshed, which is often rare for airbnbs and is a nice touch. It is summer, so only a fitted sheet was provided for me. It may have been nice for there also to be a thicker blanket/comforter, but not completely necessary given the climate.
It is a clean place and they also allowed me to store my bags after check-out before I left. If you are just looking for a comfortable place to sleep (i.e., don't need a big kitchen/lounge area), this is a great option.
