Guia answers really quickly. The flat was totally clean even though I am sure she was busy with the Venice floods just before our arrive. Her and her friend kept us informed about the Venice floods - so we would not get into difficulties when walking to the biennale.
The flat is in a very nice area with nice bars and restaurants and for me as a smoker it was great that it was on the ground floor so I could go out to have a smoke.
I can highly recommend Guia as a host.
