What a great spot. I stayed at Allyson's place with my wife and 2 children (aged 13 and 10). The house was just perfect as a base, with everything we needed to enjoy our holiday at Alki Beach. The location is great for a stroll along the waterfront, being a very short distance away, as well as easy access to the delights of downtown Seattle or day trips to such amazing places as Mount Rainier.
The house had all the essentials we needed - full kitchen, laundry, some games for the kids :) -, was comfortable and cosy, and we liked sitting outside with a morning coffee watching the comings and goings.
We were in contact with our hosts, who helped us with useful information such as where to get our groceries, as well as being available to assist with the check-in process etc.
We just had a great time - Thanks
