In a sixteen century house, a nice single room, in the center of Florence, a few minutes walking from Duomo. Private bathroom, kitchen use, washing machine, internet, courtyard, easy going... available for June, July and August.
Remember always to look the front door. Don't put music and don't speak aloud in the courtyard after 9pm. The room and the flat will be perfectly clean at the moment of the check in. It is on the guest to keep them clean until check out. If they wish extra cleaning they can agree directly with the cleaner.
