I was a host for a few months. It's a great way to make some extra cash but fatigue pretty quickly set in. Eventually I moved in with my significant other, and that was a great decision. Be prepared to be paranoid about regulations and taxes. When it comes to guests, expect the unexpected and be prepared for worst-case scenarios. Most guests are great, but some bad apples really make it challenging. Always have a spare of everything and be ready random for requests 24/7.
