Location, Location, Location. Easy walking distance to all all the main sites in Florence. About a 20 minute walk to the tram and train stations. Some of the best eats we had anywhere in our 26 days in Italy were within a 5 minute walk.
The place was spacious, clean and well equipped. With all the great restaurants near by, we didn't cook any large meals,so it's hard to rate the kitchen. However, we did prepare snacks, coffee...., and the kitchen was perfect for that. There are steps in the unit that may catch you by by surprise in the dark, as it did us. But we got used to their location fairly quickly.
There wasn't much need to contact the hosts, but when we did they were quick to respond and very accommodating. Couldn't ask for anything more from a host.
We'd highly recommend this unit and use it again if and when we go to Florence again.
