Stayed at Sussana's for 2 nights. Had a great stay! We had a heartening welcome by Sussana during checkin. She also prepared the breakfast tray a night before (had breads, croissants, cakes, tea, cherries and what not!) and had an open fridge!
The apartment is 2-3 min walk for Rialto bridge. The bus boat stop is also across the bridge. Piazza San Marco is 15-20min walk.
The apartment is on 3rd floor. The room (sun room) was neat, clean and spacious. Would recommend it to everyone.
