This was one of my best Airbnb experiences ever...a complete (and not all-IKEA!) apartment with full equipment on a quiet street south of the city center with great views over Lake Washington...but only a 15-20 minute drive into the city (and yes, you'll need a car; it's a long walk to the nearest bus.
Peter and Dah were there when I arrived, although it is also set up as self-check-in; I got the nickel tour of the facilities which includes Peter's interesting collection of items focused on Ernest Shackleton, the British polar explorer. Although I didn't use them, the facilities include a private sauna near the shower and a hot tub on a patio overlooking the lake.
Peter and Dah have several binders in the apartment with recommendations for restaurants and attractions (Jude's was my favorite). They also offered my delicious caprese salad and a blueberry crumble, ingredients from their incredible garden.
Oh, and really good WiFi...for those of us who have work to do on the road, that's important!
