Emanuele's apartment is in prime location close to downtown Florence. You will not need to use the bus/taxi to get anywhere as walking will work fine! The place has a comfortable bed and a pullout couch to accommodate a family. A kitchen and a washer (no dryer) is also available for extended stays. Be aware, the kitchen is not stocked so you should buy your own coffee, water, etc. if you want those additional amenities during your stay.
Only issue is that the only a/c is located in the kitchen, which is the opposite end from the bedroom. The cold air will not reach that far so the bedroom was very hot this August - we all ended up sleeping in the living room pullout couch in order to be cool in the heat.
Emanuele respond promptly on WhatsApp to all our requests for help which was nice.
