What are good areas to stay in Warsaw? We like to walk a lot and we want to book a hotel in an area where we can do that and see a lot. We are only in Warsaw for 2 nights and wish to maximize our stay and see as much as possible. And also we do not wish to be to far away from the train station as we are coming from Berlin by train and then going to Krakow by train.
What is the best way of getting to Krakow from Warsaw and do we need to buy tickets in advance?
