Sometimes vacations are more trouble than they're worth. You spend a lot of money, travel far, and leave stressed.

Getaway, a hospitality startup launched out of the Harvard Innovation Lab in 2015, shakes up that routine by offering tiny houses for rent. It's like camping, but with the creature comforts of home.

The company maintains a dozen tiny houses, ranging between 160 and 200 square feet, in remote, wooded areas of Massachusetts and New York. Guests can book them for $99 to $129 a night.

Founders and college friends Pete Davis and Jon Staff recently pitched their vacation startup on "Shark Tank." The pair walked away from a $7 million investment because the judges offered a "lower valuation than we thought we were worth," Davis told WTPO News.
