I've had the pleasure of staying with Joel for a few days during a conference in Washington D.C. and had great time.
The accommodation was great and the pictures definitely don't do his home justice. Joel's place is located very conveniently - only a short walk away from the convention centre, a big supermarket, cafe's, Chinatown etc.
Joel was a great host, very welcoming, and even had time to show me a few nice restaurants and bars in D.C. Thanks! :)
I would definitely recommend staying with Joel!
