The spa is definitely worth it, $22/hr! Its not the cleanest but the massage was good; you get what you pay for. Do not have high expectations here**
The spa is a large room with semi private open rooms in it, where you can hear everything from the room next door. The bathrooms are not the cleanest so if you dont have to go, just wait.
They greet you with a large bucket of warm water with a plastic bag wrapped around it to soak your feet in. When the man massaged my feet he applied just the right pressure, very relaxing.
Overall, I would go again! It's worth the price; I will just use the bathroom before going inside.
