Sarah's place is a really nice, spacious apartment located just off the amazing Campo St. Margherita. It has all the amenities you may need, including cooking utensils and basic ingredients.
It is in walking distance from most of Venice's tourist attractions whilst at the same time being located in a hip area which is mainly aimed at locals and students, with lots of cheap bars and restaurants. Pizzeria Ai Sportivi offers great set menus, particularly the special fish menu.
Only thing i'd like to mention is that the apartment is on the ground floor and therefore lacks a little light. Additionally, there is a musty smell to it, but that is to be expected in Venice.
