We spent 5 nights here, while attending a plant/gardening symposium in Seattle. It was great for us - we brought our road bikes and cycled the Burke-Gilman trail, as time allowed. We also had some great meals out, lots in the area to choose from.
Although we never "cooked" anything other than salad, the place has every kitchen gadget/dish/appliance you could ever want.
Very comfy bed, and sofa/chairs. We've often found this lacking in other rentals we've done, so we were very pleased.
Overall, we had a great stay, and would definitely come back, the next time we need to come to SEA.
