On arrival you pull up in front of the Main house, you'll find the AirBnB just behind by taking the path to the right. Let yourself in with the keycode provided and you are presented with a lovely homely feeling house which has pretty much everything you could need during your stay. It might be a little further away from the center of town (using the Space Needle and MoPop as reference), but a short Uber hop to the University light rail and in will take about 20-30 minutes if you aren't hiring a car.
The bed is super comfy and there's a big fridge freezer to stock up your food if you'd rather cook at the AirBnB and also take advantage of the hot tub (with maybe a glass of wine or two!)
I'd definitely consider coming back the next time I visit Seattle
