Airbnb is still my go-to for affordable lodging. (Before Airbnb, my go-to was Priceline Name-Your-Own-Price.) We just got back from a two-week trip through France that was comprised of stays at 7 different Airbnbs. Fortunately, we went 7 for 7 (meaning that all were as expected or better). Our average lodging cost was $55/night. All but one of those Airbnbs was a private room, with the remainder being an entire apartment. All but one of the private rooms came with a private bathroom (which we typically consider a must). We stayed in/around Alsace, Annecy, Chamonix, Lyon, Aix-en-Provence, Antibes, and Paris. Using Airbnb takes work and can be frustrating, but I find the savings (and other benefits) to be worth the effort.
