What should I photograph before moving into a Travelio unit?

Everything, with visible timestamps, on the day you get the keys. Walls at close range — stains are the single most commonly disputed deduction. Floors, skirting, and any existing scuffs. Every appliance, switched on and working, including the refrigerator and air conditioning. Furniture, including the underside and back of anything upholstered. The bathroom, including grout and any mould. Meter readings for electricity and water. Then video-walk the whole unit narrating the date. Send a summary to Travelio in the app chat that same day asking them to confirm the condition in writing, and screenshot their reply. That reply is the document you will need.
