Unfortunately I did not met Alessandro but instead of him I met Issota in charge of Alessandro. Issota was realy friendly and immediate in any question I had before my arrival but also during my stay in Venice. The appartment is really close (Tip : buy ticket for the public-water bus, and from St Stae you are really close to most of crowded places). The spase was adequate, clean, providing everything (though we were mostly strolling around Venice) so we did not used the kitchen facilities. For sure is a pleasant and quite place to stay and looking forward to visit Venice again!
Ciao!
