Amazing old fashioned apartment, 2 minutes away from railroad station. Not very big, but good kitchen, large living room and two good bathrooms.
Unfortunately, no air conditioners. I haven't noticed them in any other houses, so it may be the city rule to keep facades untouched. Anyway, in end of May it was good to live with just open windows.
Note: Do not forget your map: it is so easy to get lost in Venice.
