Susanna's place, Casa Gottardi is a wonderful place to stay in Venice. It's location is literally 200 meters from the Rialto bridge which make the Rialto and Mercato vaporetti stops easily accessible.
Susanna met us at the door and spent over 30 minutes orientating us to her space, showing us where our breakfast tray would be waiting for us in the morning, and giving us ideas for restaurants in the neighborhood.
For it's central location in Venice, quality of the accommodations, and a very caring host, we recommend you check out Susanna's place.
