A short bus ride from the vaporetto stop at Lido, buses very regular. A really nice area, close to the Excelsior Hotel in fact the balcony overlooks a quiet canal and the hotels private jetty. The apartment is everything Marta says - comfortable beautiful rooms, good kitchen and washing machine which was very useful as we had been travelling for a week with our teenage daughters when we arrived. We were met by Marta's lovely neighbour who showed us how everything worked, and also got up to see us leave at 6.20am!
I would recommend the apartment to anyone who wants to visit Venice but not be stuck in a hotel room, vaporetto travel is easy quick and regular, get a pass and it will save you money.
This is a real home from home and you couldn't be more comfortable.
