Internationally-minded Belgian living in The Netherlands.
As a guest: I'm not a fussy guest: most important is a comfortable bed, a clean bathroom, and that your place is as you describe it to be. I am a social person who is up for a chat, but I also expect my privacy to be respected. I will also be respectful of your space and belongings.
As a host: I am happy to have guests, that is why I have a guest room! As my day-to-day is quite busy (mostly with work) I do appreciate clear arrangements about arrivals and departures so I can plan.
