A very nice (and super clean!) apartment not more than 15-20 minute walk from the center of Florence. Master bedroom is very spacious, and our two kids loved their bed in the loft space above the living area (side note: because that loft space is open, it would be difficult to, say, watch tv or a movie in the living room below, but we did manage to sit with a glass of wine and chat while the kids were snoozing upstairs). The patio space is great and would be a big draw in warmer weather. Even better for us was the free private parking in the garage next door, as we were on a long road trip and needed a place to stash our car for most of our stay but also wanted quick access for the one day trip that we had planned.
Chiara and her colleagues were great -- quick to reply, flexible with check-in time, and very helpful. They left a few pages of notes in the apartment for us -- sightseeing tips, walking itineraries, and recommendations for restaurants -- and those were as good or better than what you would find in any other travel guide.
