Mario Apartment has a few locations so just gotta make sure if that’s the 5-8 min walking distance one or 20-25 min one (Santa Croce) I’ve lived in. My Mario Apartment is only a few steps away from San Stae waterbus so Line 1 the most frequently travelled line will make the place greatly accessible! Neighbourhood is quiet for those who want to stay out of the crowd yet still close to the waterbus stop and 15 min walk to the Rialto Bridge! It’s safe at night for sure in Venice. There’s not much light near the door though fyi.
