This is a great spot right near Alki beach. The apartment is tucked away from the main traffic and the view out of the dinette is a great one - especially on mornings where you can see the water.
If you have little ones, it is right next to two playgrounds and a giant recreation field.
In general I love the West Seattle neighborhood - it has a pretty low key vibe and in addition to Alki, has a few other little mini 'downtown' areas that are a short drive away.
(One caveat - if you are here during the week, getting in and out of West Seattle during rush hour can be a big pain - just plan accordingly. )
This was my 3rd stay - so I definitely can recommend it. I will be coming back next time I'm in Seattle.
