It's a very nice flat with all the right appliances in good working order. It is a good central location, very near the Duomo.
If you're going in the hot season we suggest you close the shutters if you're out during the day. This keeps the flat cool. There is a fan in the sitting room and an air conditioning unit in one of the bedrooms.
It a traditional building with high ceilings and lots of space but tastefully decorated with all the mod cons.
It's not cheap but, being in the centre of Florence makes that more understandable. Pretty good value for money.
