Hello @Amina259 and welcome!
In my welcome book I start with a big welcome to the property and include our phone numbers for contact if necessary.
Next comes WiFi info and settings.
Next is emergency numbers for police, ambulance, fire, etc. Just in case of emergency. Location of nearest hospitals and emergency clinics.
Diagram of the apartment with emergency exits.
Operation info for all appliances, stove, microwave, air fryer, even the electric kettle! It may seem easy to us but if someone is not used the language or using any of the appliances, it could be a challenge for them. I know this sounds strange, however I have experienced quite a few questions. Especially if the guest is travelling form Europe or Asia.
Next come recommendations for restaurant eating nearby, grocery stores, gift shops, etc. and their locations.
I add business cards from these establishments.
Next bus transportation, bike rentals, Uber, taxi info.
All this I place in a binder and each page has plastic sleeves to prevent wear & tear on the pages.
Good luck with your business, I hope this helps!
Cheers,
Sally
