Same room over and over again!

When Harker first enters Dracula's castle, we see a stairway to his left and a big room in front of him. He notices another door, goes through it, and is once again in the same room--except now, it's dressed differently. The stairway is still there, however. Now we see a huge table and a fireplace to the right, on the other side of the room.

Dracula arrives, introduces himself, and brings Harker to his room. They walk up the stairway and along a hallway, then turn left...and they're at the bottom of the same stairway again (only now, it's at a different angle, we see it face-on). We cannot see the rest of the room to the right. Later, when Harker hears a noise in another room, he enters, and it's apparently a library, dominated by a huge globe. To the right is a fireplace, the same fireplace that had been burning when Harker arrived. To the left is a chair surrounded by curtains, but if you look closely and quickly, you can see the stone staircase hidden in the shadows.

So, Hammer was very efficient and knew how to dress sets beautifully and economically. But once the same room was pointed out to me, I notice it every time!
