Martin is a professional. He is clearly done this before. He is polite and lovely to deal with while letting you know where you stand as a guest in his home. I really appreciate this, there is no need to tiptoe around Martin because you know what's up. If anybody has ever shared an apartment on Airbnb you may have experienced feeling like you're getting in the way, and you're not entirely sure what's annoying and what's not annoying. I feel like Martin has seen it all before. Treat him like a professional and you will have a great time.
