If you want to spoil your mood, throw money away, tickle your nerves, contact Algol. From 16.07 to 05.08 we went to Bulgaria. In the bus - dirt, cockroaches were crushed by the whole bus; drivers are rude. During the entire trip, almost no valuable information from the guide. Toilet on the way - very often in the woods (well, why don't you use a bio-toilet).
