Only in the capital some close to western standard lodging can be found, in the smaller cities and villages you must take what can be offered. Contact the head man of the village if you find nothing at all. I found it best to park the car in a village, notice the head man and eventually sleep in the car.
Prices vary from 80 us dollars in Conacry and down to 10 or 5 dollars in smaller places.
