We stayed in Seattle from the 19th of December to January 1st as a holiday vacation. That vacation was in turn made exponentially better by the stay at Claire's location. Here is a quick pro/cons list:
Pros:
1) Claire was immediately responsive as well as her husband. During our check-in, there was an unfortunate bathroom issue that once notified about, was instantly taken care of. As well as snow and even a tree falling down.
2) Great location
3) Street Parking was easy.
Cons
1) Shower is a bit small for my husband who is about 6'1.
2) You can hear noise coming from their house as they are on top of you. While they are not loud as it just appeared to be a happy kid playing, if you are not used to condo living, it may bother you.
Overall despite the two mentioned cons, we would happily stay at Claire's the next time we visit Seattle. She provided everything and more you could ask of a host. If you are needed a place to stay close to downtown, this should be the first place you look.
