Overall, it's a great place. Pros: It's quiet, clean, and it has air conditioning, which was a blessing, but can be rare in Seattle. It's right next to a park, and there are trails leading to the shoreline. The kitchen is well stocked, and the internet worked perfectly for work from home. I never heard the neighbors.
Cons: The only real con I can think of is that the second bedroom doesn't have AC, although it does have a ceiling fan. If you leave both upstairs bedrooms open, you could probably get some of the cool air from the main bedroom into the second bedroom. Of course, that should only be a problem for a couple months of the year. It's a bit far from downtown, if you need to be there. It's about a 2-mile walk or a 15-minute drive.
I would definitely stay again.
