If you're comfortable staying at a stranger's home while travelling, iStopOver is a service that connects travelers with locals renting rooms—at rates well below local hotels. The service functions much like a hotel search engine, you enter the city and the dates you'll be visiting that city and iStopOver returns the available rooms for rent. You can check out pictures of the location, see it on a Google Maps mashup, the available price, and if the room has been rented consistently even see ratings from previous visitors. Everything is handled by iStopOver, including the transfer of money between parties. When you arrive at your selected location you give the owner a code which they use to tell iStopOver that you've arrived. If things aren't like they promised you can leave without ever "checking in" and iStopOver will refund your money.Perusing the listings in New York yields a surprising bounty of really nice accommodations for prices radically better than any hotel would charge for the same accommodations. The site will list prices in Australian dollars, but there weren't any Australian listings when we checked. Is it worth the savings to stay in a stranger's home?
