While I was initially somewhat skeptical when I heard from everyone in his building that "Mark is the best" I can now add my voice to the chorus. Mark has done everything in his power to make my stay beyond enjoyable. For example, upon learning that I like cold brew coffee, Mark stocked his fridge with a couple bottles from Trader Joe's just for me. He truly went out of his way to welcome me into his home (which, by the way, is sparkling clean, and amazingly decorated), frequently offered me lunch/dinner (he's a great chef), engaged me in fascinating conversations (ask him what he thinks about self-driving cars), and even helped me move into my new apartment after my checkout date. If you have the opportunity and the means to stay with Mark, do so -- it's truly been a privilege.
