Our stay in Florence was absolutely lovely, due in great part to this fortuitous airbnb choice. Our host was incredibly accommodating and responsive as well as friendly and clear in his instructions. We were given a map and insider tips on the area as well as a fully equipped, lovely flat to comfortably spend our time in.
The flat is on the second floor (33 steps) so wouldn't be suited for someone with low mobility, but was very easy to reach and in a stellar location, being right by the main market and just a few minutes away from most areas in the city centre.
The kitchen light would flicker from time to time but that was to be expected in an older property and most likely something that will have been sorted in the near future.
Overall, this was a wonderful experience and one we would gladly repeat. :)
