If you ask me how many days should you spend to travel around Poland - I would say at least for a week so that not only you able to cover both Krakow and Warsaw, but Gdansk (one of the oldest cities in Poland) and Wroclaw. Unfortunately for me, I was pressed for time and therefore, only managed to spend four days in Krakow and Warsaw and yet, I found it's still insufficient enough.

HOW TO GET TO WARSAW FREDERIC CHOPIN AIRPORT
My flight from Warsaw to Helsinki was estimated to depart at 9am. Therefore I decided to leave my hostel earlier. Luckily the bus stop is located just right in front of Dream Hostel and I don't have to worry about catching up the bus. Took bus #175 heading to the airport using the 24-hour ticket I bought a day before. The trip took about 30 to 45 minutes, depending on traffic and hence, it's advisable to plan your journey well.
#1: The bus stop in the Old Town "Plac Zamkowy" but then, this is not the bus heading to airport. (For illustration purposes only)
