This is a wonderful place to stay in Florence - I will stay again in a heartbeat!
Quick summary: Five star location, Five star hosts. The unit is comfortable (lifts, ACs), functional, and clean.

Details:
The location of the apartment can't be beat - it is literally a few steps away from Duomo, and everything else that Florence has to offer. The apartment has two rooms - one is a master bedroom and the other works as living/dining/kitchen area. There is a comfortable full bed, two ACs - one in each room (yes, we needed ACs in September), clean bathroom, a kitchenette (kitchen in a closet), and the building has a lift. There is a Nespresso machine as well! The apartment is naturally bright & airy - there are large windows in both rooms. Overall, the unit isn't very large - the bedroom doesn't have a ton of room to move about and the kitchen is in a closet. This wasn't an issue for us, as we would trade some less space for the phenomenal location that this unit offers.

Azadeh was a great hostess - she was quick in responding to our messages, walked us through the details of the apartment when we arrived, had a ready list of recommendations for sights + restaurants + gelato shops + grocery stores, helped organize a cab back to the train station at short notice, and even helped with luggage as we were leaving.

Overall, a great and warm experience. Highly recommended.
