Before you post your listing, you’ll be asked for the city you’ll host in. Just pick the city nearest to you if you’re not located within its borders.
The city you pick needs to be within a reasonable distance of your experience—especially if you’re not providing transportation.
Guests will be able to see the location of your experience ahead of booking, and long distances might deter them from booking somewhere remote. Or maybe that’s exactly what they want! Just be clear when you name the experience and provide location descriptions.
