I just ordered a copy of the book and will have a look next week. I'll post a review here and comments (additions, edits) as soon as I can. I know that a lot of the material is subjective, so please take my feedback with a grain of salt.
On Amazon, you can "look inside" a good part of the book already. I thumbed through what is available to read for free. A few initial comments - 1) it drives me crazy when anyone refers to the First District or Innere Stadt as the "Old Town" as no one here would ever refer to this area in that way - no local would know what you are talking about, especially as this district isn't particularly old; and 2) the public transportation maps are misleading (the U2 purple line hasn't and won't be running between Schottentor and Karlsplatz for a long time; the O tram line is referred to as the 0 tram line, which is a thing I think as locals will have no idea about a "zero" tram line). I recognize that these two points are negative, but I am sure I will have plenty of positive things to say soon.
Stay tuned...
