Everything you read in these reviews about this great apartment, the fantastic location, and the personable, helpful Francesco is all real. We can add nothing to what has already been nicely said in all these positive reviews. We loved it; we would come back in an instant; we have recommended it to everyone who asks about our trip.
One recommendation we could add: Turn right after leaving the apartment then take the first right down the alley to the Piazza della Passera. There you will find at least four good restaurants, any one of which would be a good choice to try. But the best thing there is the Gelateria della Passera, which may have the best gelato in Florence. Lots of great, unusual flavors -- try the cream with 7 spices or the chocolate/orange or the mint ....heck, at only one euro per scoop, try them all!
