If you're looking for a place to stay the night before getting on a Norwegian cruise ship, this is a great place to stay. You're super close to the pier, and we found that we could check out right at 10, head down to the pier, and only had to wait about 30 minutes before boarding. And the building was very secure, with secure parking.
As for the place itself, it was very clean. There is only one portable air conditioner in the unit, so if it's warm in Seattle, you may be a bit uncomfortable at night with the bedroom door closed. The place is smaller, more designed as a one bedroom unit for the business executive that wants a place to stay in the city rather than two couples to stay in two bedrooms. The second bedroom is tight, and there is only one bathroom. The apartment was quiet, with the location out of the way with little foot traffic.
