You travel on a budget, but you’ve abandoned grimy, noisy hostels for the cheapest of Airbnb stays. Or maybe you’ve always assumed hostels are dark, sad places packed with sweaty backpackers, and skip them altogether.

From tree houses to former universities to veritable nightclubs, hostels come in all sorts of vibes and venues. Great ones will enhance your travel experience in addition to saving you money. And though guests tend to be on the youthful side, most hostels will allow you to stay at any age.
