6 stars is not possible so I gave 5 stars :).
Easy to find, 5 minutes from Mestre train station (not Santa Lucia). Even though they don't speak English, you won't have difficulties.

Super clean rooms & bathrooms just like in the pictures. Almost like staying in a small hotel.

Easy access to restaurants , super market & the train station.

If you are looking for a room in Venice, you just found the best one.
