I booked this apartment in the beginning of April. This apartment was very nice: big square, large kitchen with all necessary kitchenware. The main advantage is a perfect location - close to bridge Ponte-Vecchio. In the location you can easily visit all sights in Florence without any buses (e.g. you need only a couple of minutes in order to approach Uffizi Gallery). The host was very polite and he quickly explained me all necessary details concerning to the apartment and the city. I recommend these apartment for all tourists!
Only one desire to all visitors: please, do not forget your earplugs (fortunately I took them), because after 11 p.m. and until 1 a.m. all surrounding streets become very-very noisy (crowds of noisy tourists, drunk teenagers and et. al.) and your night dream may be very problematical...
