The flat is located in the historic center of Florence with walking distance to all sights as well as the central station. The room was clean and comfortable, it even has it's own shower.
Alberto showed me everything. He made sure I understood how to use the keys, since there are many different ones.
Drinking water is for free which I found extremely useful.
Overall it was a great experience. The only deficiency for me was, that because of the great location I could here a lot of noise though my window until 1 o'clock or so. I found that very distracting because I wanted to sleep earlier...
