Be sure to check if Bill will be in town during your stay -- based on other reviews, I'm sure you would have have a great experience. We were here when he was out of the country and had several problems that would undoubtedly have been fixed immediately otherwise. First, the A/C was not working properly when the temperature got above 80 degrees -- we suffered through 9 hot afternoons, and it wasn't dealt with even during the week that Marco was in town. Second, the basic level of promised housekeeping -- clean sheets and towels once a week -- needed a reminder from us during one of the weeks. Third, the dog was let out to poop in the backyard every morning, and without the main hosts in town it was not cleaned up until the next day on 9 occasions. Fourth, some of the kitchenware are obviously discarded hand-me-downs and would benefit from upgrading.

The pluses -- and we did stay for our full term of 17 days --
1) fantastic location, nice neighborhood
2) bicycles provided (at least one desperately needs basic cleaning and lubrication, but that still is a great benefit in Venice)
3) the bed and shower/bathroom were fine for us

My impression of Bill, via email, is that he's the kind of person who will address the negatives we experienced as soon as he is able, so future guests will probably benefit from that.
