The place was awesome, even with two kids we managed to get sleep and they pull out bed was more comfortable than you might imagine. Gretchen was a great hostess who made sure we had everything we needed (even included a pack n play for our infant and offered to wash some clothes since we started so long) but didn't invade our space either. It felt like we were staying with family. Thanks again Gretchen!
A couple notes I would make is to be prepared if it's going to be hot that it gets rather warm inside but most places in Washington don't have AC because it's really not needed and doesn't get that warm more than a couple days a year. Also, there isn't a kitchen in the place, which is actually indicated on the list of amenities, but I personally overlooked because I assumed "entire place" meant kitchen. We ended up eating out mostly anyway, although Gretchen included a large hotplate if we really needed to cook.
