We stayed here for a month so really got a good sense of the place. We enjoyed our stay. There are a lot of attractive elements: the location is great, it's spacious and the check in was very easy.
The unit does need some TLC/maintenance: It gets very cold (window fan isn't sealed properly), but there is a space heater provided; there isn't a recycling container and recycling is required in Seattle; cat poop in back and soil all over top of fridge upon arrival, unpruned thorn bushes poking out into narrow pathway from the parking spot, and few other small things.
Overall, it was good stay and we would stay again if we weren't charged $100 for leaving some hair in the shower drain and burning popcorn in the microwave.
