The apartment is in a great location in the centre of Florence a few minutes from the Duomo and Ponte Veccio and has a fantastic view over the city (which comes at the price of lots of stairs -- take note if you have little children or find stairs difficult). The facilities - wifi, washing machine, dishwasher, air con etc - all work well and the terrace at the top - up a further flight of stairs - is a joy in the evenings as the sun comes down. The living room is a pleasent pleasant place to relax after sightseeing in the heat - when the air con comes into its own. There are good local restaurants very close by - pizza on the terrace is great - and a supermarket/shops; Claudio has provided some recommendations and a map etc.
Very much recommended -- we travelled as a family of four with two teens.
