Don't look any further than Domenico's apartment when visiting Florence.
It's a studio apartment in an excellent location, a short walk from the station, and within a few minutes walk of Duomo, Uffizi gallery, Ponte Vecchio and the best gelati shops.
It is not large, but is well equipped and makes efficient use of space. It is very quiet despite its central location. The clothes washing machine and drier were an added bonus. It is up two flights of stairs without a lift.
Domenico is a great host. We didn't meet him, but he was always available by phone, text or email. He responded promptly and sorted out any issue without delay, you only had to ask. We ate at two of the restaurants he recommended. They were better experiences and cheaper than the ones we found for ourselves.
I would definitely stay here again if I was returning Florence.
