Bus travel in Turkey is a right choice after flight. Bus companies has great services, bra new buses, comfort, wi-fi, tea/ coffee offer, Tv with earphones etc. Only the problem is while buying ticket you may need someone who can speak english. If you go to a bus company office more less all of them has no english speaking person and what if you ask them they will say ok no problem. But that is mostly time people get shock because you may get on wrong destination bus easly. That is the reason you better buy your bus tickets from a travel agency which has English speaking Person and they will understand you correctly and get the right informations.
