The apartment was incredible - much bigger and lovelier than we expected - pretty central, on the 2nd floor of an old building on a quieter street. Keycode access to the building and apartment is very easy and convenient. Even though it's so central it's very quiet and peaceful - it takes less than 10 minutes to walk to the Duomo and is no more than 20 minutes walk from other sights in Florence. After a day of walking Florence, it was lovely to come back to the peaceful, cool sanctuary of the apartment. The decor and design is lovely - modern and stylish like a boutique hotel.
The AC works extremely well (it was over 90 when we were there in mid-June) and it was great to have a washer, iron and full kitchen including dishwasher to use.
It's in a great area close to the library and there are also bars and cafes at the end of the street and a little patisserie a minute's walk away. It's a wonderful apartment and I would definitely stay there again as well as recommend it to anyone visiting Florence. Fantastic!
