Hotels still don’t cut it. Usually a stay needs to exceed some length of time needs (due to the cleaning fee typically being flat in Airbnb’s) before it becomes worthwhile. But if you’re in that camp (4+ people, 4+ days) it becomes pretty worthwhile. The cost savings on food alone makes it back up pretty quick, plus there are other savings usually related to parking being included etc.
