as noted on their listing, the space is older and slightly rundown aside from the recently-renovated bathroom. I got the impression that someone actually lives in the space and/or stays there quite regularly based on the half-used spice packets and other open food items. Also the top of the stove was rather dirty, and the collection of glasses and cups in the cupboards was slightly odd (lots of shot glasses!) On the upside we were welcome to use any of the food in the house if we wanted, so it was very homey that way.
On checkin day I let them know we'd be arriving in Seattle on the 2:30 ferry, and they responded that they would "aim for" 3:00 (which is the listed checkin time). At 3:15 I finally received a message with my checkin password, and we walked in to find the dishwasher running.
It was comfortable enough, and the location was good for our purposes. If you book this place be sure to communicate about your intended arrival time well in advance. I don't know if I would actually stay here again, but it wasn't bad for the price.
