Oooh, this was very sad and angsty and H/C in the first part and then just showered us with fluffyheartlove at the end! Yay for schmoop.
Also, I really *love* your Snape-as-concierge. I'm sure he was very, very good, elegant and efficient and knowledgeable and quiet. So much so that guests would note he had a way of just "seeming to appear when you needed him," and that "he had a way of knowing what you needed, practically as though he could read your mind!" :D
