Great location a bit away from the city center, but that was what we were looking for. Very close (5-7 min) to Pitti Palace, Santo Spirito and Boboli Gardens. Grocery store just a few minutes away, too (Carrefour Express). 15-20 minutes to city center. All the kitchen items you will need. Good AC.
Our 12 and 14 year old slept on the pull out couch, not the most comfortable, but it worked for the 4 nights.
Grazia's son met us and was very available when a fuse blew, he was on it right away.
The washing machine was broken and by an earlier comment seems to have been so for awhile. They should get this fixed or remove it from the listing.
