One of the best ways to cool off during the summer heat is takingadip in the pool, but what if you don’t have one? Swimply is sort of an AirBNB for pools, and allows strangers to rent pools at people’s houses. The site features houses with pools all over the country, and you can rent them for however long they want, although there’s usually a one hour minimum. Some even come with amenities like barbecues, although many have rules on the maxium amount of friends you can bring with you. Rental prices do vary but some are actually under $100 an hour, so if you and four friends want to go in on it, that seems pretty cheap.
