Great location, OK hotel
I have stayed here for one night on 3-4 different trips in the last 6 months. The location is amazing, a 3 minute walk from the south end of baggage claim. If you fly into the A or S terminals at SeaTac you're in the hotel room within 30 minutes of pulling into the gate. Also, the light rail is a 5 minute walk from the hotel. 
The hotel and rooms are worn in places as others have noted. My rooms have always been fine for a quick turn and the hotel has been quiet. Most rooms are large and have a desk. The staff has been great. I have not eaten at the hotel and I would expect the food to be fairly simple. 
My only complaints
- the trash truck woke me up at 4am and the same morning the alarm was preset for 5am 
- the front desk missed a wakeup call, but my alarm went off on another visit 
Bottom line, I'll return for 1 night visits before/after flights.
