This is one time when the experience was so good that one hesitates to give it the review it deserves for fear of it being booked solid the next time one wishes to go there.
The host, Elisabetta, has clearly considered in full the needs of the her guests in detail, and is a sparkling person with a fine sense of humor who speaks English well and made sure to give us a detailed description of all of the amenities in the apartment. The bed is excellent and in a quiet bedroom, the fridge is large, the stove is gas, and there are all the necessary utensils. Two minor matters that could be imporved amidst the excellence: a larger Bialetti espresso pot, and we couldn't find the cutting board, if it was there.
The location is superb, right behind the Uffizi and the large livingroom/kitchen is fills with daylight. When we arrived, our train was half an hour late, Elisabetta and her husband, Claudio were there to greet us, and he carried our two largest bags up the stairs, which was certainly appreciated.
It's rare when one's expectaions are exceeded; this is one of those times.
