Very impressive & convinient place to stay even if you don't get the car with you. There also free spaces around the Akiko's place to park your car.
First you get there by the Link, it's quite far from the station, but you can use many buses to go to the downtown easily, I actually recommend to use the bus:)
The kitchen are nice and has almost everything you might want for cooking although we actually didn't use the kitchen to cook something but toasts only, because we ate out when staying there.
I didn't have any troubles for staying there, and check-in/out was very simple. Live there & Enjoy Seattle :)
