Wonderful place, great views and amazing location right on the beach! We would definitely stay there again. Easily fit a family of three (with a 4 year old). It would be a bit tight for more than 4 people. Overall very kid friendly (e.g., curtains or shades with no cords). Even had some sand toys! Note that it does have a shower only, no bath tub. In terms of noise, we were there in mid-September. The was some noticeable noise from the beach and live music at a bar next door, but that quieted down after 10 pm. Some of the cars on Alki avenue are also loud, but again, that mostly quiets down after 10-11. We did not notice much noise from the daycare on the ground floor.
