My wife and I stayed two nights in Tim & Kelly's Ballard Backyard Bungalow and we'd definitely stay again.
It's a lovely and quiet residential part of Ballard where we had a very easy time finding free street parking each time we came and went. It's within walking distance of some pretty eclectic and fun parts of Ballard, including new local breweries, a fantastic biscuit & coffee place and the incredible Ballard Farmer's Market on Sundays.
The space itself is unique and comfortable. We were there on hot days and the fan system inside the space was perfect for us. The bungalow is located around the back of the house, as a separate structure, via a beautiful walkway, which felt private and cozy. We felt an added protection due to the bungalow being on an enclosed-yard property and not open to the streets.
Tim and Kelly have some great notes and area tips inside the space, which were both thoughtful and useful. We loved the book collection available in the built-in bookshelves and left with a few more titles to add to our list.
