We stayed three delightful nights. We found a private parking space, a modern well-stocked kitchen (with a big bowl full of treats--thank you!), a cozy living/dining area, excellent beds in the bedrooms, and a full bath with an actual TUB. Another unexpected plus was the washer/dryer, complete with supplies. The Ballard neighborhood is eclectic, close to lots of interesting shops and sites. This house is also only two blocks from a city bus line that goes to downtown Seattle. The WiFi worked fine.
The main apartment is a second floor walk-up in an older home with lots of character. One of the bedrooms is a converted attic space with skylights. Our last night we had rain on the roof--what a wonderful way to sleep! We did not use the Airstream, but it looked really cool in there.
