Paolo's apartment is in a very good location. I was staying in Florence for a month for work and this was perfect because it is located outside the city in a quiet street, but you can easily get to the center by bus and tram.
Paolo is a great host, he responds quickly and he is very helpful and kind. The apartment has it's own bathroom and kitchen and the bed is really cozy.
The only complaint that I have is that the dishes and the pots in the kitchen were not clean and I needed to wash everything before use. Also the kitchen could be better equipped. Since I was staying there for a month, I needed to cook so I was missing stuff like knifes, cutting board, scissors... But for someone who is there for a short stay maybe that would not bother them.
