We had a wonderful stay at Marie's apartment in Florence. The location is excellent. Just a few blocks from the Ponte Vecchio, but not in the middle of all the tourist madness. The apartment is up a steep hill, not a problem, but something to be aware of. It's in a lovely residential area with grocery shops near by (as well as some excellent shoe shopping). We stocked up on coffee and milk for the am, in the apartment, and had all of our other meals in Florence.
Marie was great. Prompt, reliable, and gave us good local tips for food and flea markets (both personal favorites to explore).
The apartment is just lovely. Beautifully appointed with eastern touches, ample books (including guides to Florence and Italy). Good wifi service, quiet, nice natural light, and well appointed with what you need.
I would definetly stay there again! And highly recommend it.
