We had a great stay in The Burrow for our first trip to Portland - we loved how convenient it was to walk to the MAX train into Downtown, the collection of restaurants to choose from within a block or two, and the neat atmosphere of the basement apartment in this quiet residential area. Plus, it was a short and generally traffic-free drive to and from the Expo Center (which is why we were in Portland to begin with!)
One particular of The Burrow itself that I appreciated was the two-room arrangement. I get up a couple hours before my wife (usually) to read, and having the ability to have the lights on in the living space and keep the bedroom door closed was a plus.
