Ken is a great guy! I had an unusual scenario where I rented his room for one month to transition a permanent move to DC.
From the day I showed up, Ken was very helpful. He provided me with a parking pass to keep my car on the street, helped me carry my things in, and even offered to let me store a few things that wouldn't fit in my room elsewhere in his home.
Day to day life was pleasant too. Ken is a great combination of present should you need him but also frequently doing his own thing, so you don't feel on top of each other all the time. He's also a great guy to talk to about politics!
