Francesca's place was very clean and tidy, which is by far my most important consideration. The bed was very comfortable and the location was within walking distance of everything. My husband and I really enjoyed our time there.
One thing to note is that if you are a particularly light sleeper the sounds from the street below may keep you up. This is to be expected in a city, but there are some quieter areas across Ponte Vecchio.
Like I said though, great, clean apartment in an area central to everything. Francesca is extremely nice and communicates very well. You won't be disappointed!
