I don't know how long I'll keep at it, but for now until I stop, I'm going to post an Alley of the Week.
There are a lot of great Seattle alleys. The one behind my building is exceptional. It's raised, it's gated, and the art galleries (Kucera and Foster/White) put sculptures out on it. From S Main to S Washington, between 3rd Ave S and 4th Ave S. The back of the Union Hotel faces it at its north end. You can see the Tashiro Kaplan Artist's Building beyond.
