Why did I not know about this before? The vicarious thrill of "walking" around Snape's office is just too much fun. Mind you, it's not a thing as I imagined it -- where's the fireplace, for instance? And like the Potions classroom, those windows hardly cry out "dungeon" -- but there are a lot of neat little touches. Definitely worth looking at if you've got high speed, or perhaps even if you don't (although I wouldn't know -- ha ha).
