My wife and I had a great 2-night stay thanks to Elizabeth and Chris being terrific hosts! Location is good too. Totally walkable to shops and eats, and we uber'd around the rest of Seattle. This was the first Airbnb stay for either of us so we didn't know what to expect.
Objectively, this space is a basement, but the homey touches make it feel comfortable. This space is great fit for those who just need a place to sleep between exploring the city/otherwise busy most of the day.
As guests, we could easily and readily hear noise (footsteps mostly) from upstairs, so it'd be difficult to sleep in while folks upstairs are getting ready for work in the morning.
The worst/most disappointing part of our stay was the shower. The extremely low water pressure from the shower head did the job but was less than desirable.
