We paid $125 per night, with an additional $25 charge for early check-in. I feel this was pretty overpriced for what we got, but it was short notice so it's understandable.
The place has almost everything you need, but it does feel like living in a basement. Expect at least one spider to show up.
There's a handy laundry room, which is also a bathroom. The kitchen exists but is pretty bare minimum: sink, microwave, toaster oven, coffee maker. There was coffee grounds but no sugar or milk. There's a living room area with a couch but no TV; it just faces the kitchen counter.
Safeway is a 10 minute walk away, which is handy, and you can Uber most places around Seattle in 20 minutes or so.
Ultimately, it's a decent place to stay for a day or two.
