Jayson's apartment is immaculate. Super cool decor, great location, extremely clean, comfy home away from home. Communication was fantastic (as were arrival and check-in directions). Jayson was traveling in Europe while we were in Seattle and he answered incredibly quickly leading up to and during our stay. I travelled with my teenaged sons and twin beds were set up for them in the guest room. We had a late-ish arrival and were coming from EST, so that was a nice touch.
If you have long hair, bring a hair dryer. There is one there, but it was the size of my hand and not super effective. That is really the only "negative" I have to say.
One other thing: You are in the city and it is noisy. There were sirens (police and fire stations a couple of blocks away), people on the street, cars, busses, etc. That is not a bad thing. But if you are a light sleeper, you might want to consider earplugs. This is not a negative about the apartment but rather a caveat for those who may not be city-dwellers or used to normal city hubbub. Don't let a little noise discourage you from staying in a great place! We all slept well (but we have a highway behind our house so...)
