EQ is a very good host — he is very respectful and maintains his space well. He also provides necessities that some others do not — like water, cooking wear, hand soaps, hand towels, etc.
With that said, please respect his space. It is an old building, so where flip flops to protect your feet on the floor. Sometimes other guests will not maintain the public spaces properly or follow the notes left by the host - do your part to help out and your stay will be better because of it.
