In order to save money, many people choose to forego staying in hotels in favor of hostels, short-term rentals like Airbnb or home swapping arrangements. NightSwapping is a platform that lists free accommodations, which is literally as inexpensive as you can get.
Instead of paying to stay somewhere, NightSwapping lets members earn Night credits for free lodging. If you let someone stay at your place for free, you can earn these credits and use them to stay elsewhere. The Nights you earn are equivalent to the stay you offer. Listings are also grouped according to the standard of accommodation, with luxurious and popular homes being worth a greater number of credits.
This home swapping service clearly works as well, with more than 100,000 members in 160 countries.
