Me and my friend met Dj during our trip in Addis Abeba for a conference. We asked our hotel for a city day tour and they called his agency. He is a very nice person, he knows his country very well and love it. We visited the main cathedrals and the National Museum and we enjoyed together the lunch in a tipycal restaurant.
He speaks an excellent English. If I came back in Ethiopia I would absolutely call him. He isn't a guide, he is a friend!
