We loved our stay in Davide's apartment. It is very central but away from the tourist madness. The decor is very Venetian which makes for a special experience. We travelled with a 2 year old and a 2 month old and it was perfect for our needs. Davide very kindly arranged a cot for us. The apartment is on the first floor and there are about 12 steps to the front door. The main bedroom and living room are air-conditioned, and there is a washing machine. There are some nice cafes and restaurants close by, as well as a pharmacy and a supermarket within a 10-15 minute walk. It's close to several water bus stations which are on line 2 (which services all the main attractions). Water pressure is a bit weak and WiFi connection was patchy but I think that's pretty common in all places in Venice and neither of these were deal breakers. My tip is to ask to meet the property manager at San Samuele station for check in as it's much closer than San Angelo, which is important when you're lugging bags around.
