Katia's flat is in a beautiful, peaceful area but within walking distance of everything you'll want to see while in Venice. The apartment is in a gorgeous traditional building, well decorated and very spacious. I would highly recommend staying a little further away from San Marco and Rialto than you might think looking at the map - you get so much more for your money and nowhere is actually very far to walk. The vaporetto and airport ferry stops nearby, and there is a supermarket, restaurants and ice cream parlour all close by too. Do note that Katia asks guests to correspond by email - worth knowing in advance in case you are not comfortable with this.
