Room numbers here can be confusing - they are laid out like a clock. Rooms like 100, 200, etc are on the east side, 225 is north, 250 is to the west, and 275 is to the south. 299 is next to 200.
There are men's and women's bathrooms on every floor, but they swap sides; first and fourth floors have men on the west/cafe side, women on the east/entrance side. Second and third floor are reverse.
