What a lovely spot! Quiet, cosy, full of thoughtful touches and in a great location. A great base from which to explore Seattle, or for a staycation which feels like a world away from the city despite being right in the heart of it.
The one caution I would share is for light sensitive sleepers: bring a sleep mask! There are a lot of windows - great for views of the garden, not so great for sleeping in. In particular, there is an unshaded skylight almost directly above the bed which is bright even at night due to the city light pollution.
