We stayed in the Guest Rooms once - Student Center 1st Floor - under the Cafeteria area.
And stayed in Burman Hall twice. Those rooms are regular dorm rooms with linens and a sink area. The community bathrooms are kept clean as well (for toilet and shower). You can't beat the convenience & nor the price of 37/night when you just need it for a night's sleep.
If you call and everything is full - call again closer to your arrival date, they usually have cancellations (just no waiting list).
