We had an excellent time in the Northern Lights cottage. For a really fair price we basically had an entire house to ourselves: full bath and kitchen, living room with direct TV--the works!
West Seattle is a cool neighborhood, it's quiet enough but filled with cool bars and restaurants. The C line bus takes you to downtown or Fremont in half an hour.
Although we didn't get a chance to meet Laura, check-in was easy and convenient. We always felt confident she was available should the need have arisen.
The only downside to an otherwise great find on AirBnB is the bed in this cottage. It's rather small (more towards a twin than a queen) and not too comfortable. Other than that, I would definitely recommend this cottage.
