The communication with my guests when I meet them personally is the most important ocasion to leave a grood impression.
The previous written communication can sometimes be very one-sided, because the guest does not react until the day of his arrival, although he receives a friendly welcome message. Well, th few lines of text or the ratings of my guests are usually not enough to get a good impression of someone.
The moment you first (and possibly only) meet, that's what matters. Good posture, friendly appearance, sympathetic natural smile, no hurry or hectic rush, eloquent language, but also a tactful feeling. Small talk serves to find out more about the guest. Whether the stay is of a tourist or professional nature. What do I communicate, what not. What are the priorities?
Not every guest wants to be directly seen as a family member. Some even feel uncomfortable with too much attention. As host I hold myself back with things to my person as long as a guest does not explicitly ask me. The guest should be in the foreground. Knowledge of human nature is essential.
