Fantastic stay at a wonderful apartment.
We were driving from San Gimignano and didn't realise we wouldn't be able to park anywhere near the apartment. For anyone planning to stay who has a car (which was unnecessary for getting around Florence) I'd highly recommend using the parking lot behind the Hertz (address below), it's a secure place to park and cost us €36 for 3 days which I thought was reasonable. From there it was 25 minutes by tram/walk to the apartment.
