Yari's place is excellent. It was spotless and nicely decorated. The surroundings are just beautiful and quiet, away from the clutter of the city, still close enough to visit Firenze using public transportation. There's a bus route (38) that passes every hour a stone throw away from the apartment. If you miss that one, you can always walk some 12 minutes to get to Via Galileo where you get buses 12 and 13 passing every 15/20 minutes.
Yari was an great host, kind, helpful and responsive.
This is certainly a place we'll look forward in our next visit to Firenze. My wife and I loved it.
