Getting over the fear of saying no. We are not the most child friendly listing. We had a young couple with a 2 month old beg us to allow it for Christmas and they left one day into the three day stay giving us a 2 star review because our old wooden floor squeak waking the baby up and they never slept more than 20 minutes. We apologized profusely and refunded the rest of the stay but those stars hurt for the fact we thought we were being nice by allowing them to stay. Just be nice but firm and say no.
We have a triplex, rent two and live in one. After having air re-home people trying to sneak in extra guests we message everyone upon booking to say we live here and will be meeting you. This curtails a lot of shennanigans before they begin.
