This is a perfect basecamp for the Biennale, tucked right between Arsenale and Giardini. Located on the far side of the island, it is an easy trip on the Vaporetto from the main station followed by a quick and short walk (only one bridge, so great for luggage). Venice is quite small, so it is easy to get around to all the sights, walking or by boat, but this place is just far enough outside the tourist core that you can actually get some peace and quiet and feel more connected to the local routines of the city than that of the hoards of tour groups. This respite really makes a stay in Venice magical.
There is a grocery store nearby if one wanted to settle in and cook in the kitchen, but there are also a number of good restaurants on the main street nearby.
Elisabetta was really responsive and checking in to the apartment couldn't be easier.
A great spot!
