In short, flat's outer beauty: 5/5, flat's inner beauty 2/5.
Flat's location is central and the flat is roomy and cute. However you see issues during and after you move in the flat. The host was 30 mins late than the agreed time for check in. There was a piece of hair under the tower hanger and the hanger just fell down after I put the towel inside, it is broken. Same for the bin in the kitchen, the top is broken, you have to touch the bin to open. Also there were only 3 little shampoos and 2 toilet rolls left for 4 nights stay of 2 people. And most importantly the heaters don't work until 1 November. The temperature at night in Florence could go down to 5C in October so no heaters mean cold nights. Also the flat receives an extreme amount of noise from the street, it is like you're sleeping on the street, zero isolation makes it impossible to get a good night sleep.
