Warszawa its a very nice city with its own history and nice places to visit and enjoy tere...

Be careful with pickpockets in the underground. And always leave your car on a guarded parking site.

There are no ticket machines so better get one before kiosks are closed! (a 24-hour, 3-day or one week ticket is a good idea).
Otherwise you will be imposed a fine, tickets are mostly checked in the night!

Never think of riding bike in a street - keep to the pavement or you'll get smashed. Drivers in Warsaw are famous for their bravado and tend not to see vehicles smaller than theirs. Never leave your bike in a solitary place, bike theft in Warsaw is a national sport and there is no mechanical method to avoid it but simply to keep an eye on the bike.

Hotel Hera and Hotel Sokrates are good options if you have any links with Warsaw University ... perhaps even otherwise ... Polish soups are earthy with a decidedly 'Polish' flavour to them, not to mention the lovely pierogies and the black currant juice ... and the city is amazing from the viewpoint of its reconstruction after WW2 - so painstakingly done to such good effect - that it is worth visiting sites with this specifically in mind ... a central transport hub too if you are headed anywhere east from Western Europe ... to Belarus, the Baltics or Russia ... be careful in the central train station though as also on trains (the ones to Berlin were notorious at one time, in which you could be gassed and robbed as you slept) though things have improved now ... and Polish train rides are utterly romantic...

Ask the taxi driver for a price before you enter a taxi , else they rip you off...

Home town. Lot to talk about :)

don't visit Plac Szembeka by night ! ;-) 

No Danger in the city, hotels are expensive

A wonderful showcase of the old and new. The contrast from a ultra modern democratic Poland and the blandness of its communist history. Churches on most every block. All unique and beautiful. The city square (in old Warsaw) is picturesque and a great place to watch the people walk by. It is a custom of the locals to walk to town on Sundays. The old city square is a great place to eat and drink.
