You can leave all over Turkey and almost all over Europe: Greece, Bulgaria, Ukraine, Germany, etc..
You can have a delicious meal. There is a metro station nearby and a huge new shopping center within walking distance. At the metro station in the shopping center building, there is a currency exchange at a Good rate in a jewelry store.
When buses depart, sellers walk around the salon, offering all sorts of useful little things.
Each bus company has a waiting room, usually also its own toilet and in some places free coffee or tea, all companies have free Internet via WiFi.. Tickets are bought immediately. There is a direct bus from the center to the new Airport.
The huge Istanbul bus station. Buses all over Turkey and to neighboring countries, Bulgaria, Romania, Greece, Ukraine. Both the metro station and a small shopping center are here.
Ottogar railway Station is the only possibility of direct access to Bulgaria. There are buses from the airport, but they are only at the height of the season. It is a 30-minute drive from the new Istanbul Airport. You immediately fall into the arms of an obsessive Turkish service. Who offers you a perfume like a real one. Someone is luring you to eat. Menu without prices: only pictures. If something has confused you and you promise another time, then a monologue in Turkish sounds little like a declaration of love. I paid 40 euros for the bus to Sunny Beach. Promised for 6 hours. In fact, I was driving 10.Moreover, the intermediary who caught me also asked for a tip. Although the bus was quite comfortable. Only at the border for 2 hours. We have already been stopped twice in Bulgaria in order to find illegal immigrants in the trunk!
