This apartment is perfect! It is very nice and clean, with a big bathroom and it has a very well equipped kitchen. Temperature in the apartment is easily adjustable. Most important though is the central location of the apartment, it is a short walking distance from Duomo and all other "must sees" in Firenze. For breakfast you can go to any cafe at the river side, which is max. a 2 min walk.
Mine is a great host, great with communication and takes fast care of things!
