I loved staying at Luca's place! The Giudecca is great to get away from the crazy tourist hustle, and just one vaporetto stop away from it all. There is a great grocery store right downstairs, and a wonderful fish seller etc. on the main drag. I was there for eight days and cooked most meals - I saved a lot and didn't have to eat at the crummy expensive restaurants. The place was quiet, clean, and well-appointed. Bed was firm (!). Roof deck was nice too. I got some work/correspondence done with the wifi. It is a contemporary apartment (like where people from Venice actually live/work) - not old-school Venetian. I'd stay there again.
