Isabella has been a splendid host. Communication was quick and efficient, and she's been very friendly and flexible.
The apartment is great, and as shown in the pictures. It's not big (especially the bathroom), but it's very tastefully decorated, cosy, clean, and it comes with all the amenities one could need.
The best thing is probably the terrace and the view you enjoy from there. It's just great to have all that green in the back, and the magnificent view on the Arno and the historical center of Firenze! (which you can reach in 10-15min by foot).
A big plus is also the fact that it's pretty easy to find a place to park your car in the immediate vicinity of the apartment.
All in all, highly recommended!
