Quite centrally located, about 10 mins walk from St Mark's Square aka Piazza San Marco. Michela is very nice and patient. She explained all the details, including apartment tour as well as local tips around the area. She is also accommodative, as she allowed early check in at 12noon and luggage storage after checkout at 11am till 1pm.
The apartment has a big living space, esp the living room. It is on the second floor of an old building. It has the nostalgic 16th century feel. There's a nearby pizza shop that sells great mega size pizza.
