If you want a super clean, very modern, comfortable and safe location that is very quiet then you cannot beat Beatrice's apartment. It is located in a typical Venetian neighborhood with very few tourists comparatively speaking. Very small cafes and restaurants pop up around 5 in the afternoon. An 18 minute walk along the canal back to Pizzale Roma provides you with bustling restaurants and the main transportation center for waterbus' to the main attractions of the city. To pay 7.5 euros per person for a 3 minute waterbus ride from station Santa Marta to station Roma is not worth the expense in my opinion.
