The apartment was very clean and Franco was very accommodating of our late (airline induced) arrival. Be aware that the owner will have to meet you at a prearranged location/time to show you where the apartment is, give you the key, collect the rent, and give you a tour of the apartment. If you have any travel faux pas, this can be stressful. Though not his fault, calling Franco from a payphone at the airport was expensive and difficult.
The apartment is removed from the highly touristy area, making it considerably more quiet (though there is foot traffic past the ground floor bedroom window all night--something to consider if you will sleep with the window open). The apartment had been updated, and was furnished with older items. It was about a 5-10 minute walk to Plaza San Marco, and about a 1 hour walk to the train station. (FYI, Venice is an incredible maze! Make sure to get a map as soon as you arrive. You can't get too lost--you're on an island...but you may never find your way back to your lodging!!).
We were disappointed on a few points. The listing advertises WiFi. There was none that we could access from the apartment. We actually chose this apartment in order to have access to the clothes washer, and we were told that we were not allowed to use it. Lastly, it was our understanding that the owner was supposed to meet us to collect the key when we left. He never arrived, so we had to hide the giant skeleton key (you couldn't lock the door from inside).
