Great hotel, we all liked it.
Wonderful hotel, very close to the airport. We took the LINK light rail ($2.75) from downtown to SEATAC airport and arranged to be picked up by shuttle. The driver was very pleasant and very friendly, made small talk and very polite. Quite a different experience from what I normally get from shuttle drivers. What a nice touch. Even when we left at 6:30AM, the driver was also super friendly and courteous!
At check-in, the staff were nice and courteous. She explained the hotel amenities in detail and made us all felt comfortable and not rush.
Our room is nice but it did not have a view (we overlooked another building's roof and a bit of the airport). However, everything in the room is great, we ordered pillow from the "pillow menu" and they were all there. The room is clean, spacious and lovely, the bathroom is spacious and the tub is very large.
The common area has malt balls, chocolate covered raisins, cheese sticks, yogurt and bottled water. Nice touch.
We also dined at the restaurant - Copperleaf. Originally we wanted to take advantage of the happy hour menu and drinks, unfortunately our children are now allowed at the bar area so we sat outside the bar and was unable to take advantage of that happy hour perk. However, we ordered from the Copperleaf Menu and the food was very excellent. The wait staff was friendly and knowledgeable and the food was delicious.
We were impressed by the kids menu, the choices were great! The highlight was the fruit plate, both kids said "oh my, you should taste what I have just tasted!" 
Our main dishes arrived very late which was the low point of the meal, but they apologized many times and comped us for some items that we ordered.
All in all, a fab hotel and restaurant and we will go back.
If management is reading this, here are my suggestions (they are minor):
1. The desk chairs in the hotel room cannot be pushed all the way under the desk because of the high armrest, hence taking up space in the room. 
2. Water pressure on the shower head is low, I would love a bit more.
3. I like the free bottled water in the common area, but I feel that it is not earth friendly.
4. This happens to most hotel -- the coffee pot is the only way to get hot water for my tea, but that made my tea taste like coffee... 
Again, this is a very nice place, I really like it.
