I found this website (
http://www.inyourpocket.com/) that has a lot of city guides for European cities. You can buy them online but some they have for free in pdf format...

There are two types... there are the city guides which are the group on top and those are the 8+mb pdf guidebooks which have some good info in them. then the ones below that are the instant guides which are like 350kb or something and like 6 pages long of stuff thats handy to know.
those are the downloadable ones. all the other ones you can view online (not in pdf form, just webpage format) or buy.
it's a strange variety of cities they have, but could be helpful at somepoint.
