This place could not be better located: on a lovely street (up a hill, so be aware), close to Ponte Vecchio but not in the middle of madness. The view is beautiful (you can see it from the Uffizi) and it is comfortable. Lots of space, so in a way ideal for more then a couple. We didn't get a chance to meet Diana in person. Her partner, Frederica, was waiting for us and checked us in. They were both very pleasant and responsive. It was a cold weekend in Florence and they were quick to help us get the heat sorted out (which ordinarily is off by this time of year). They went out of their way to accommodate us, getting a and extra wi-fi key when theirs was in use by another of their clients (they have a business of renting apartments in Florence). Also delivered an iron that was missing, were helpful in calling a taxi for us for the return to the train. Apropos, though it is only a 15 - 20 minute walk, I recommend a taxi from the train unless you know Florence well, as the most obvious path to walk is right past the Duomo and Uffizi, and then across Ponte Vecchio which are almost always packed.

Nice place. Easy access to Florence, including Piti Palace and some great places to eat on the south side of the river.
