In the BWV 1 Bedroom, the safes are in the closet off the Master bedroom - actually the closet opens into the room with the jacuzzi tub. I do not know how large the AsM safes are - the ones at the BWV are small. IIRC, you could get travel papers, and wallets in, but not purses or laptops. You can leave things with the front desk if you need more space or better security.
Best wishes-
