If you ask me whether Warsaw is enough for a weekend trip, I would say YES-You can enjoy the most of your 2 days with tasty food,rich culture and eventful history. But if you ask me 48 hours is enough for Warsaw? My answer is NO. What Warsaw can offer you is more than you can expect. If possible, please leave at least 3 -4days to this city which you may think it has not too much left after the heavily destruction during World War II.
