Absolutely brilliant little cabinet of curiosities. The wife and I had a great time in Georgetown, great lunch and dinner options right around the corner (try the torta at Fonda La Catrina!), and we felt very comfortable in our tucked-away corner of the city. Stash the car in the lot outside and take the 124 bus into the city, and you'll have yourself some very fun walking tours of Seattle, and all without worrying about parking/getting a window smashed on vacation. The kitchen is also very serviceable.
Couple things to note: the mattress has a bit of a dent, take a moment when you get there to figure out who fits where. And taller folk beware, it is cozy up in the loft and you'll want to take care not to smoke your head on the windows or the frame. We visited during a pretty harsh cold snap and found the heaters quite adequate to stay toasty even in the biggest room.
Best vacation I've had in a long while, highly recommended. The Museum of Flight right nearby was incredible!
