I stayed at Derek's place while visiting Seattle for work. It was a charming, clean, and comfortable basement studio, on a quiet street a couple short blocks from Broadway E.
I slept on the double bed, which had a firm foam mattress that I found very comfortable. The kitchen appeared to be very well-equipped for cooking, though I did not end up using it since there is a such a great restaurant scene in the area. The wi-fi worked perfectly.
