The building where the room is, is very old and has no elevator. It was very hot and noisy, as in the street are many tables of the restaurants.
The bathroom is very old and not clean. The owner lives in the flat.
The communication was not so good, as Luisa answered in Italian, even if I wrote in English. She did not allow to leave my luggage until 11 am.
The room is big and the bed is comfortable.
The location is good if you look for Trastevere.
