We thoroughly enjoyed our stay in Seattle at Harbor Steps.
The location is excellent for exploring the city and relaxing in the evening. The apartment is located just a couple of blocks from a light rail station, which serves the airport; it's also near the ferries and water taxis as well as restaurants and Pike Place/Public Market. We walked or took the light rail everywhere except the Boeing Plant Tour (about 30-40 minutes away via car) and the Museum of Flight (accessible by bus line).
The apartment is spacious and boasts nice views of the harbor.
We appreciated being able to check in early as former guests had already left and the room had been cleaned after we arrived midday (after a long flight from the east coast). We were also glad to be able to store luggage after checkout and before our flight left later in the evening on the day of our departure.
Debra was responsive and kept me informed of any updates relating to the apartment. We'd definitely stay here again on a subsequent trip to Seattle.
