I'm the sort of person who would rather pay a bit more for a place I LOVE then a bit less for a place that's just okay or so-so.
Kimberly and Joshua's place was easily worth the slightly higher rental fee than we might have paid elsewhere. The flat was light and airy with plenty of room for our family of four and some truly gorgeous views of the sound.
The hosts were friendly and very responsive, and only suggestion I'd make is that they leave some written instructions for how to log in and use their Apple TV.
We would definitely stay there again the next time we're in Seattle..
