A self check-in works when the guest never has to guess. Every doubt becomes a phone call, usually late in the evening.

The five things to write down

  • The exact street address plus a landmark ("blue door, left of the bakery").
  • The building or gate code, then the door code, in the order they are used.
  • Where the key box is, and how to close it again.
  • What to do if a code fails — one phone number, clearly labelled.
  • The check-in window, so guests know when the flat is ready.

Write steps, not paragraphs

Numbered steps beat long prose. One action per step, in the order the guest performs it, with a photo whenever a detail is hard to describe.

Keep a short reassurance note at the end: guests who know someone is reachable call far less often.
