Renee has a lovely cottage that is a cozy abode for a solo traveler or couple. The house is just a 5-10 minute drive and a 10-20 minute walk from the heart of Ballard, and the soundscape of the maritime neighborhood -- the occasional (and distant) horn from a passing barge or train, seagulls, church bells -- adds to the ambiance. Street side parking is easy and plentiful, and Renee and her partner live next door, so they're on hand to deal with any infrequent (and minor) issues you might have.
The 5 rooms -- living room, bedroom, kitchen, bathroom, and mudroom/hallway -- were exactly what I needed during my ~2.5 month stay: the living room has seating for four -- 2 on the couch, 2 chairs -- with a TV connected to Netflix, the bed is comfortable with two drawers of storage, the tiny bathroom is well-heated with a clawfoot bathtub, and the kitchen has all the amenities you need to cook during your stay -- stove, oven, electric kettle, microwave, coffee maker, and a few other appliances.
The only downside is that the house is in an AT&T dead zone, so phone calls get sketchy sometimes, but that was only a minor issue during my stay.
