The apartment is very centrally located in Florence, only a half block from the Ponte Vecchio. It's got a lovely terrace, which my wife and I used to enjoy an aperitivo before heading out to dinner each night. The rest of the apartment is quite spacious with a kitchen (mini-fridge, freezer, and stove top), sitting room, and bedroom. The air conditioning definitely help as we visited in late May.
We also made use of the host's restaurant recommendations. They were great places to eat and saved us a bit of research.
