Had a great time at Antonio's place, location is perfect, communication with the host was great and I had full support throughout my stay. The place was clean and Internet was working fine.
Would like to note though, personally I'd recommend this listing for someone who's been in Venice before as you need to be aware of prices/availability and what you're getting for your money. The same dates in a hotel would've costed almost twice the price, and for me it was more important I can walk to vaporetto stop in seconds or that there's an awesome fritto misto take away minutes from the place...it is small, more "a single student" accommodation but I wanted to spend money on eating out, opera and biennale - so consider your priorities. The listing is accurate, the place is perfectly located and clean, and I had a great time there, despite no lift in the building or not the strongest water pressure, but hey it's an old building in Venice and it was within my budget.
