To say that this place is perfect is really an understatement. My sister and I stayed for four nights. We have crashed at many different airbnbs, too many to count, and Bernie's home is truly one of a kind. The space is set up like a studio apartment, with a pull down bed, comfortable couch, full kitchen, bathroom and laundry. We woke up every morning, over looking the mountains and the lake. There is a great patio in the backyard overlooking the mountains; immediately adjacent to the door to the airbnb. Oftentimes, we crossed paths with Bernie and/or her husband. They were overwhelmingly hospitable; to the point where we seriously felt like we were living at home with family.
While in Seattle, we explored downtown. It was about a 3 mile walk to the city center. But the bus line is very easy, and there are tons of bikes everywhere you can use by downloading an app ($1 an hour). On our trip, we also made it to Vancouver in about an hour and a half.
If you are looking for a beautiful, comfortable place to stay in Seattle (just outside of the downtown area, but very affordable), Bernie's is highly recommended. We will absolutely return if we ever find ourselves back in the area.
