The Guest House was a place designed by the Toy Maker, meant to entertain visitors with shows and dance. After the corruption of the Toy Maker, it became yet another one of his series of traps.
- In the stake chamber, the song of Vampire Killer is played. Which previously was used in The Music Box from the first game.
- The red bridge that is destroyed by the Keeper of the Void Sword has several faces of the Puppet Master painted on.
- If you look above the large head containing the entrance, you can see two Hunchbacks attempting to saw off a large bell, presumably to hinder Alucard. Keeping the camera on them for a few seconds triggers an achievement called 'Not Again...'
- Amusingly, the elevator in the room with three dungeon keys has a sign that says 'no wolves allowed'.
