The two most important aspects of a place to stay are location and a comfortable bed with parking as a bonus. This place had all three. You were within 15-20 minutes walk for every tourist activity in Seattle and when you came back exhausted you had a great bed to sleep on. Being able to just park the car and forget about it made it great. We loved the roof top deck and wished we had more time and opportunity to use it on our visit.
There were a number of downsides though and know them before choosing. There is no dish detergent, no soap, no paper towels, no salt and pepper, no pots and no pans. I choose Airbnb because I like to cook breakfast before starting the day, not an easy task when there is nothing to work with. When I see a stove and kitchen advertised I assume there are supplies to actually cook with. Same with the washer/dryer, I see it advertised, I assume there will be detergent, there wasn't and I don't travel with laundry detergent.
The biggest draw back though was the lack of AC in the unit. I know that Seattle is never supposed to get hot but we were there for four days of 80+ with blinds that don't close with west facing windows, the place was uncomfortably hot. There was a portable AC unit that was not installed. We opened the slider and placed the unit close to the screen using sheets to cover the window, it brought the temperature down to tolerably warm.
I also admit to being a tree hugger and it bothered me there was no set up for recycling. I have no problem with being a responsible person and would at least like the option. We did find a recycling container in the garbage room and used that.
The pros of the place out way the cons but know going in what you are getting into.
