It is a shared living unit, you rent your own room and share the bathroom with 3-4 other rooms. Inside our room the toilet flush / pipes from either from next door or from a neighbour above the unit were loudly audible. The room itself had sort of folding beds / sleeping couches, one single sized bed and another small two sized bed.
The location of the airbnb is amazing, very close to the St. Angel Castle and the historical center of Rome.
Overall we were not satisfied, since it didn’t meet our expectations of comfort by far. For what we paid, we expected more comfort and privacy - even for a shared living unit.
If you are travelling on a budget and don’t care so much about comfort, it might be just right for you. For us it wasn’t.
