Airbnb's website says that "best practice" is to keep the lockbox in your building, but the guest can't enter the my building without a key. Where do you keep it in ?
Usually lock-box are best placed outside the building to allow guest for a smooth self check in process.
I’ve considered putting one myself but then I always feel disconnected with my guest so I prefer meeting and putting a face behind the listing and the name 🙂
