We had a great stay at David's apartment in Florence.
The apartment is spacious and in a great location - not in the middle of the touristy areas, but in walking distance - minutes away from the Ponte Vecchio.
We were greeted by David's partner, who walked us through the apartment and even gave us a map with tips of where we could eat, drink, shop, etc.
The only thing to note is that there are a few floors of stairs to walk up - something to consider if you have a lot of luggage, and the stairwell is pretty dark. We just used our flashlights on our phones at night, wasn't a big deal at all.
