I spent 12 days in Paolo's apartment and in my opinion it's a very good place to stay in Florence. Taking into account moderate price I belive it is one of the best positions on AirBnB in terms of quality/price ratio.
It's situated ~10min walking from Santa Maria Novella station and also close to most tourist sights like Duomo, Ponte Vecchio etc. Regardless of central location it is really very, very quiet thanks to top floor and windows that don't give to any street.
The flat itself is quite little and it's more like big corridor (all chambers are in one line: kitchen-bedroom-bathroom). In my opinion it is not very cosy - I think because of white terracotta also in the bedroom which made me feel that I'm still in the kitchen :-)
But then come only superlatives!
+ Apartment has a balcony which is very convenient if you are a smoker or you just want to hang you laundry.
+ The bathroom is clean and newly renovated, has big shower, wc and bidet.
+ You can easily adjust temperature in the apartment
+ On bed I found a real, warm qulit (not typical italian coperta) which was very pleasant suprise!
+ The apartment is very well equipped. I felt almost like home - I had everything I needed. Good Wi-Fi, TV, Electric kettle, iron, washing machine including washing liquids, plug adapters. Paolo also bought some grocieres for my reception: coffee, biscuits, orange juice, fruits.
Unfortunately I didn't have a pleasure to meet Paolo face-to-face but I met his wife and she was very helpful friendly.
To sum up - I totally recommend this apartment and look forward to come back again some time.
Grazie Paolo, alla prossima volta! ;)
