Mark's place is on the fourth floor of the building (I'm not sure if his building has an elevator, so I suggest checking with him if this is important to you). I stayed in his bedroom w/private bath listing and it was absolutely spotless, with fantastic views of the city. He is fully stocked with everything you might possibly need - from shampoo and conditioner to earplugs (which you really won't need because none of the street noise comes through). I really enjoyed talking to Mark and appreciated how very hospitable he is!
