We did enjoyed our stay in Firenze and in this appartment shared between the occupants of the 2 rooms.
Sharing has, as usual, good and bad implications, depending mainly on the state of mind of the other travellers.
We had some good moments with others, but we also met people that doesn't care about cleaning the kitchen or spending a whole hour in the bathroom, while you wait for the WC.
Concerning the host, we stayed a whole week and didn't even meet Mariaflavia.
