we are planning to use the train in our journey from Istanbul to Berlin, but we are not sure if such a travel will be safe and comfortable for two girls (both 20). Firstly we don't know how we are going to be protected from thefts during the night when we are both sleeping and how much the rate of thefts in Bulgaria and Serbia is.
Something we'd also like to learn is if it is possible to choose a non couchette train and how to do it. Can we also pay an axtra fare and get a two-bed sleeper? Is it possible to do it in all night trains and how much does it cost?
The last question is if the trains in Bulgaria and Serbia are really on time and how much the delays are. A friend told that it takes much more than it is written on the timetable.
this is really the next question:): If we miss the train we'll have to wait in the train station maybe for hours and at night. Is the train station in Beograd a safe place at night?
