i visited Ethiopia with 5 friends earlier this year. In Lalibela, Kassahun was our guide.  We visited the monolithic churches in Lalibela as well as rode mules and did a traditional homestay. Kassahun is fluent in English. i found him to be a man of integrity and kind and responsible and took pains to ensure that we were comfortable and taken care of.  We trusted him and felt safe with him.
