Rosella's place was definitely cute and located in a quiet neighborhood. You still have about 10 minutes walk to the boat station coming from the train station direction. It is located away from the tourist areas like Rosella listed, so it was nice and quiet at night but don't walk back too late after 10pm because the streets are quite empty and could seem scary to tourists.
The listing says 2 bathrooms but it's technically 1.5 since there's only 1 shower (the one in the master is just a half bath). The shower is quite tiny so beware if you are a bigger than 5 feet. It was sort of expected as Venice is a small town and everything is cramp. The AC needs to be on full time if you want the entire place to be cool during the hot summer days as the units are only located in the 2 bedrooms.
It could be that we visited on the week that Rosella was out of town, communications were not immediate and sometimes had to wait until the next day for a response. Otherwise, we enjoyed our time in Venice with Rosella's place. It's just a shock coming from the US to Venice since majority of the amenities are older and smaller so need to have that expectation.
