No check-in is available after 21:00. If your flight is delayed like ours, no one will be at the reception and you would need to wait until someone comes into the building to access the apartment. We mentioned this but no solution or alternative was provided. At the check out we kindly requested to leave our luggage as our flight was departing late, but once again no solution was provided. Check-in and check-out should me managed in a better way.
