Apartment suites very nice, but...
We stayed here during a recent conference. The apartment suites are huge and very comfortable. We had some trash in the room when we checked in, which the front desk cleaned up right away. We had some issues with the batteries on the lock system which kept us out of our room, but again front desk staff were helpful as well.
My one gripe. We accidentally forgot our prescription pills in the hotel room (our fault, of course) and didn't realize until we got back to Canada. We were in Seattle for 5 hours after checkout, and calling us after the items were found would have saved me 5 hours of driving back to Seattle and a day of lost wages the next day.
