The apartment of Sebastiano is a perfect place to stay in Venice. It is only 1 minute from the San Marco. The apartment is on the 5th floor. So if you don't like walking the stairs, perhaps it is not the place for you.
You have a lovely view from the windows on the gondola's in the canal. In the morning and evening you will see the gondola's leaving and coming back. There are two spacey bedrooms and two bathrooms. Communication with Sebastiano and his sister was very good. We were heartily welcomed by Sebastiano's sister. I sure will recommend this apartment.
