However, his English was excellent and we soon found out that he was an English teacher before the war. We agreed on a price for showing us the entire area during the next 2 days. We took a nap and he picked us up later.
The next morning we got up a little later than usual. After leaving our room we recognized that this town and region was stunning. Desert and high volcanoes all around us. The place was superb.
