This place is probably in the best location in the city. The uffizi is located just around the corner, which allows you visit early and beat the crowds. Palazzo Pitti is just across the nearby Ponte Vecchio Bridge, and the Duomo complex is a 10 min walk through a lovely pedestrian zone. The nearby food is fantastic, with a great restaurant for steak florentine next door and the famous antica Viaio foccacceria nearby. Wait until just before closing or right at open to beat the huge line ups for the most amazing sandwich you have ever had. For dessert, the nearby Gelateria Neri has the best gelato I have had in the city and always has a long line of locals.
The place was spacious, very clean, and exactly as shown in the listing. Sandra was a great host giving us a smooth check in and local tips. I would recommend this place to anyone, but especially those with children (the bunk beds and master bedroom would be perfect for a couple with 2 children). The washer worked well and detergent was provided. The two complete bathrooms with shower were great with plenty of hot water.
Note that as advertised it is on the 1st floor and there is no elevator, BUT it is really only half a flight of stairs up and was not strenuous to climb (approx. 10 steps).
