Can anyone offer me any good advice? Things to do in the winter? Good clubs in any of the cities?
Things to do in the winter: stay warm
Good clubs: Klubokawiarnia (the pseudo underground vibe with old PRL decor), otherwise just ask around when you are here and people will tell you what's cool..
Another good tip-if you need reasonably priced accomodation in Warsaw look up the OkiDoki hostel, the location is excellent and the prices are reasonable (even their single rooms are cheap I think) I have heard nothing but good things about the place, just look it up on the web and book a room...
