This location was very convenient to store our luggage after a cruise while waiting for a late night flight. Right nearby, you can take the monorail to Seattle Center and the space Needle. Then you can take the monorail back and hop on the light rail train from Westlake station to go to the airport. It was a very easy process to drop off and pick up our bags. The location is very nice and clean, and the owner was friendly. It is located in a tattoo studio, which may sound strange, but it looks more like an upscale salon inside.
The Westlake train station is very hard to find. Just go exactly where Google maps says to go, and there is basically a hole in the wall with a single elevator down. We didn't see a sign outside at all, but there is a little one on the wall next to the elevator.
