I had stayed at this home last year and I came back a second time, since I had a great stay.
The apartment is exactly as shown in the photos. Very large and cozy. The location is perfect, being half way between the airport and downtown. All the amenities listed are actually there, as well as the private parking spot (a little tight, maybe). The check-in and check-out are super easy, thanks to the code lock and clear instructions. The communication with Krystal was near instantaneous. All in all, absolutely recommended. I will be back again next time I'm in Seattle.
