We had a good stay for four nights at Daniel's place. The apartment is very convenient to get to the main sights in Florence as well as the train/bus station which was very convenient for some of the day trips we did.
Daniel was prompt in communicating with us, and allowed us to store our luggage in the apartment a few hours early while he was getting the place ready.
The air conditioners worked very well in both the living room and bedroom. Kitchen and bathroom were very clean.
One point to note for future renters:
1. the door of the washer is broken and Daniel had to train us for 10 minutes to make sure we could open it after a wash. Florence leg was bang in the middle of our Italy vacation and we were counting on access to a washer. While it worked out OK in the end, we could have done without some of the anxiety!
