Took the Link Light Rail into the city from the airport. It was easy to find and dropped me off just a block from my hotel. One of the best things is that it was only a few dollars for a ride.
$4.50 from airport to city centre, taxi $60'ish approx. Comfortable and stops at several places. It's a fair walk from the airport terminal so request assistance if you need it.
This was the cheapest option when going to downtown Seattle from the airport. However, I stayed at a hotel near the Space Needle and the nearest stop was still a 20 minute walk. I would not call this ...
