Martina replies very quickly to emails. I met her without a problem with the directions she provided. The flat was small and simple. I shared the common area with another pair and it was fine. It was very hot and humid, but I guess that's everywhere in Venice at the time. It's located around 15-20 minutes to Railto bridge, so plan your day wisely instead of going back and forth. At night the entire area is very quiet as almost nothing is open. It's close to a supermarket so you can buy water and things cheaper than places like San Marco.
