On overall I've found this guide useful and the information about museums and historical sites provided appeared to be up to date and fairly comprehensive although sometimes a bit too laconic. However the maps provided were not so good. The map of the transport was very obscure and covers only central areas. However, if you are travelling from the airport or want to steer away from the center it's absolutely no use and I was happy that I had printed a few maps from Google, otherwise I would be lost with this book only. The same problem with the fold out map. It's basically the same map as the one inside the book, perhaps a little bit larger. But it is 90% the same map as in a book which makes no sense. It would be much better idea to have a map of the central Vienna printed inside the book and a Greater Vienna as a foldout map.
