We had a great stay at stefanos apartment. Stefano arranged for someone to meet us at the ca d'oro vaporetto stop and take us to the apartment which is very well located just off the strada nuova. You can easily walk or catch vaporetto to all the major sites. There is also a supermarket and heaps of restaurants nearby.
Stefanos apartment is fantastic. Very well appointed and spacious - we had a very comfortable stay (and we were a large group of 8)
Stefano also recommended a number of great restaurants that were very good - in particular ai promessi sposi which was fantastic
I would definitely recommend stefanos apartment for anyone looking for a large and well appointed apartment in venice
