I would like to bring you some information updating that guide.
1) in the simian mountains park chapter , you wrote that Sankaber is the only place offering basic dormitory accommodation. Since august 2011, the Hut in Glich offers as well accomodation for about 8-10 persons (80 birrs)and provides good food.
2)in Debark, the prices of the hotels have more than doubled.
A range of new hotels have opened; among them a good one name “landscape hotel”, nice rooms( 220-400 birrs), clean and restaurant
3) In Gonder, has opened very recently a very nice restaurant, welle furnished with traditionazl materials, located at the back of the public library, 200m from the exit of the fasil castle.It is the “four sisters” restaurant.
