We had a wonderful 4-night stay at Yvonne and Erik's Airbnb. The unit was above the garage in the backyard of their house. The decor was very modern and stylish, sparkly clean and very quiet. We were welcomed with a bottle of wine and snacks, and a nice list of local tips, such as things to do and good restaurants in the area. My only complaint was the TV placement was a bit strange while we tried to catch up with GoT, but it's not a big deal at all. :)
Yvonne and Erik were very responsive during our entire stay. We had some power socket problems on the first day, and Yvonne and Erik dropped by in the evening and fixed it.
Yvonne sent over a thoughtful instructions for checking in, but we had a little trouble finding the keybox and the unit entrance. Some photo instructions or signage in the backyard would be very helpful.
Overall, we strongly recommend staying at Yvonne and Erik's place for your Seattle trip. You'll have a lovely time here.
