The Luxury Artist apartment is stylish and cozy and in a fantastic location. It is easily accessible to all of the spots we love in Florence. The bed is comfortable. The views are nice. It is light and bright. Be aware that there are 74 steps (10 narrow and twisting flights) to the top of the building, which makes it tricky to get your luggage up and down, but not a problem day to day.
Communication with the 'host' (whoever they were), was frustrating. We were greeted by a woman upon arrival who was in a huge rush to copy our passports and then run out the door, without sharing any information about the apartment. (We then messaged the 'host' on AirBnB, but still have yet to receive a response.)
All worked out though, since we figured some things out ourselves and really enjoyed the apartment and our stay in Florence.
Be sure to hit Pizza Napoli, which is right down the street.
