The place is a great option for whoever wants to go have a good time in Florence. It is extremely well-located at the heart of the historic centre of the city, and two steps away from the Piazza della Signoria and the Ponte Vecchio. Great location, couldn't be better. Bear in in mind though, that this great location comes with a price: it's pretty noisy all day around and at night as well, specially on weekends (we were there from Thursday to Monday, and Friday and Saturday night were wild).
However, a couple of things that you should be aware. The place is pretty small altogether, which is not the actual problem. My biggest concern was the bathroom, since it's not very practical whatsoever, since it's very reduced. So, if you are expecting something comfortable, please know that it most probably won't. Second thing was, the stairs to go to the bedroom. They are steep and also the third step is kind of tricky since it's half way inside, and at night when going down to the bathroom it was sort of dangerous since I was close to fall a couple of times.
Apart from that, the place is excellent from a location and price perspective! If you are going for a couple of nights, it's a yes!
