I spent a month here and it was a very wonderful and comfortable place to do so. Sydney's place is well-appointed and modern, with amenities like a smart TV, coffee maker, space heater, etc. that just added to my comfort. The location is really accessible and walkable to downtown and lots of place on Colfax and in Capitol Hill.
A couple notes I think might be useful for future guests:
The host is super friendly and responsive, though also definitely not intrusive or nosy. I enjoyed saying hi when passing by or having a quick chat on the patio.
This is a garden-level floor. It doesn't have its own thermostat so on especially hot days it actually stays pretty cold because the A/C runs. It's manageable and I used the space heater a few times (which does have a thermostat on it so is easily controlled).
When using the front gate, I found it easier to always unlock from the inside lock and lock from the outside lock.
The smoke detector is pretty sensitive! I felt bad a couple times when I made toast in the morning and the sensor went off! :)
There are plenty of linens and towels - the towels are probably the softest I've ever had!
The bed is a softer bed so took some getting used to for me as I'm used to a firm bed.
