Bill's metal box was a geat place. The location was amazing, the check-in was easy and right at the door, we were notified beforehand of how to access the metal box.
The parking was a bit tight but no issue at all, I was able to easily fit a minivan in the spot, just had to let everyone on/off before/after the spot.
The house itself was great for 1-4 people max, a nice cozy place with lots of things to watch on the TV and the kitchen was equipped well and had a Keurig and Kirkland Signature cups readily available.
The room upstairs was also very clean and the bed was cozy, as was the sofa bed, very cozy.
The bus leaves for downtown right from the front, across the street and it is $2.75 for the day pass. That was very convenient. Even if you are driving, it is only ~15 minutes to downtown Seattle.
Would stay again.
