Living at Shuiyu's was a great experience. She was kind to correctly guide us to the BnB before our arrival. She was accommodative to our late-evening check-in, which was hassle-free. We stayed for four days and have nothing to complain about.
The BnB is located in a calm residential area of mainland Venice, about 20 minutes by tram/bus from Venice Mestre (preferred railway station if you plan to stay on the mainland). The tram/bus stop to the island or other places on the mainland is only about 3 minutes away by walk. Restaurants and supermarkets are easily accessible.
It's a good place to unwind after a long day on the islands.
