Hi Martina, the visit at your apartment in Firenze was great. The historical atmosphere of the house fits perfect to the old city of Firenze.
It was a pity you could not provide a second pair of keys or split the key for the power switch from the others. The ac units were loud at night, so no way to sleep with ac working (as announced in comments).
Summa summarum good location for reasonable price in the heart of Firenze.
