We've spent two nights in Adrianas apartment Adriana wasn't there herself, but one of her employee (?) gave us a short welcome.
The appartment is very nice and definitely in a great location for a short Florence-trip. We guess that you can't find a better location.
Maybe it would be helpful to inform the guests - coming by car - about the ZTL area, which you have to pass to reach the apartment.
The apartment wasn't that clean, as we expected it for an cleaning fee of 50 € (there was some hair in the bed, and in the shower and everything was a bit dusty).
We also got some communication problems, because (until today) we did not get an answer on our questions like, where to but the garbage or if there is an option for late checkout.
But all in all it was a perfect location to enjoy a short citytrip in this beautiful city.
