Get the airport bus 175 from there to centrum then you can see Centralna and walk to it. ZTM-put it in google.
Yeah the airport part is the easy one, I rather take a cab to Centralna though. Because of...
If you take 175 stay alerted while on the bus as it's infamous for groups of professional pickpoceteers "working" it.Don't let anybody get to close to you and if possible take a seat.
So my problem is about trains, and cabs as well, are they safe? Can I take a cab from Warsaw Airport?
When you get to Warszawa Centralna, there are ticket machines which menu is also in english so it shouldn't be problem to buy a ticket.
That's quite a surprise didn't know such thing existed in Poland. Though I rather book the tickets(online) prior to traveling for two reasons.
a)Once im in Centralna I might find that there aren't seats available in any train to Lublin and I need to be in Lublin at some fixed time, for the scheduled check-in in hotel.
b) I would really like to have some "hard evidence" that i'm going to Lublin, just in case the immigrations officer requests. If I have a hotel reservation in Lublin but no ticket to Lublin he might be suspicious. Since i dont live in the EU I would really like to avoid any problems...
Rent a car at the airport and then drive wherever
Renting a card is tricky, first i would have to know about polish transit rules, which honestly i don't know. Then i would have to learn how to travel by route in Poland, seems harder and I have also heard that the roads are not particulary safe. On top of that my driver's license would have to be authentificated in Poland, and that looks fairly complicated.
Thanks people for the feedback, any more help is of course vastly apreciated.
