The host was the quickest of the many I contacted in replying, very welcoming and helpful. The apartment was very clean and silent, despite of the very central position (the street's right in front of Santa Croce church). Perfect place to rest after a whole day working. Only not so good detail: it's on the third floor with no lift and pretty tall stairs, but you'll find that every apt in Florence is the same, that's why they're so fit. It wouldn't have been a problem at all to be honest if I wouldn't have been crazy loaded with my working gears.

So, yes, I DEFINITELY SUGGEST THE PLACE AND THE HOST.

P.S.: forget your car.
