This is a very good apartment, with a bedroom facing the canal, located in a quiet street behind the 'Ospedale'.
You can reach the public transports in about 10 mins (not in 4 as claimed) and S. Marco in around 15 mins. On the way to S. Marco you also find the famous Libreria Acqua Alta, a very special bookshop facing a canal as well, with a particular way to keep and store books.
There is no wifi provided, which depending on your dataplan can be or not a problem. Often you find free wifi at bars and restaurants, so if you are cool with that, it's not a big deal. I personally just bought a paper map and did not check the internet for 5 days—a real treat.
The place is clean enough, you can cook and in general chill. There is a fan but not air conditioning. Keeping the windows open at night in the bedroom facing the canal (there is a second bedroom), did the trick for me in late August.
