When the vacation budget doesn't stretch to upmarket hotels and 5-star resorts, Airbnb is a great way of finding one-of-a-kind stays for reasonable prices. From log cabins in the mountains to artsy lofts in the country's coolest downtowns, we've found the best Airbnb under $150 in every state (with prices correct at the time of writing). Just remember to double-check state travel advisories before you head out.
