Hello! I was thinking about going to Istanbul but the train connection in the east parte of Europe is a bit difficult to understand... I'll be in Budapest and I think that the best way Is to go to Bucarest and from there I saw there is a bus... Do you know if the bus Is included? I don't know how to understand if the bus Is part or not of the ticket.
And, to come back, I need to go to Vienna after, do you have suggestions about the way to follow?
