Perfect position! A short walk from a waterbus (vaporetto) stop and also the alilaguna waterferry to the airport. Literally the best position for getting in and out of Venice.
The apartment is amazing. beautifully decorated and a comfortable space. Best shower and the most modern place we saw in all our Italy travels. The only tiny negative is that this apartment is on the 4th floor... but this is only a problem once when you're taking your bags upstairs. After that it's a non-issue.
Dorsuduro is where you want to stay in Venice. Close enough to the tourist spots (8mins walk to St Marks) but far enough to not be overrun with crowds and overpriced food and drinks.
The aircon is heaven in the midday heat and you will love the generous space. Thomas the host provides you with all the info you need and more. Book this apartment for sure!
