The Art Apartment was extremely conveniently located for everything we wanted to see and do over a short stay in Florence. It was clean, and hosts were quick to respond to any questions.
Check in was rushed, but largely because we were late due to issues with parking (would not necessarily recommend this location for those with a car due to extremely limited parking in the city and ZTL issues etc). Despite this, hosts gave excellent local tips and left a bottle of wine which was much appreciated. One further thing to note is that the mezzanine level was quite creaky and did not feel convincingly structurally sound to walk on. This would probably not be such a concern for less heavy visitors.
Overall we had a really excellent stay and would happily recommend this apartment to anyone visiting Florence.
