This place is amazing! Clean, well maintained, and with great locations. The beds were really comfortable and there were plenty of towels for everyone. In addition, it's well stocked with toilet paper, paper towels, and even laundry detergent you can use.
We also noticed there was a sauna in the basement, but we didn't get to use it. Probably great during winter months.
The only downside is that there is no AC in the unit, so it can get warm during the afternoon. However, Seattle never really gets that hot and the place was cool at night.
