Overall, I was pleased with my stay. It was a good location, (about 8 min by car from the Seattle Center) and had most of the amenities I needed for my stay. My only issues were small ones: 1) when the sofa bed is out, it's a pretty cramped area to navigate around. I wish I had moved the chair before I put the bed down. 2) If you leave the bed down during your stay, there is no real balance of privacy + light since you are on display if the front shades are up.
The listing description of the shower is spot on. It's indeed small and cramped. I'm a petite 5' 4" and I touched the ceiling of the shower when washing my hair. And while not an issue for me, I think it bears note that there was no TV or microwave.
That said, it was clean, there were homey touches, and a fairly well-stocked kitchenette including burners and a toaster oven, which was nice. Ample street parking as well!
