We highly recommend Piazza Ciompi! Sid was extremely responsive, answering my emails within minutes. He was ready to hand over the keys and show us the place when we arrived, and he even helped us to unload the luggage and came with me to find a parking garage along the narrow streets of Firenze's old city (better to take the train though!). This write-up might just sound like a glowing review of Sid's service, but before he even showed us the place we were excited by the view of the Duomo from the front of the building. Then when he showed us the place, we were amazed. Sid told us that it the building is around 700 years old, but clearly it had been extensively renovated. The apartment was clean; very spacious with great, arched ceilings; nicely air conditioned with separate units and controls in each room; and lots of beds (8, I think!) and bedrooms. The kitchen was stocked with everything we needed, and even had a dishwasher. Plus, we had a washing machine. Our daughters loved the large garden, which "came with" a turtle (they fed it lettuce). Of course, with a location like this, we tried not to spend too much time in the apartment because we were just a few blocks from Santa Croce, the Duomo, the Synagogue, and plenty of gelato! When I booked the apartment, I was worried that it seemed to good to be true... but it was perfect!
