Well, to be honest, what is really the difference with other detailed map? We expected more scholarly map since this is used for Taxi and PCO licence exam preparation. Yes, its big and detailed, and the embassies and other major addresses are well indicated, there is mort much difference . However, if you were buying a property within 6 miles of Charring Cross station, id set, Central London, this is a good information material to keep. For people who do not need detailed map for Central London area, this is not necessary. For tourists visiting London, this is the map to have, and as always, Amazon has the best price. Make sure you buy directly from Amazon or Fulfilled by Amazon to avoid bad sellers who do not send or send unsatisfactory quality.
This map is for students studying "The Knowledge" to become a black cab driver, so concentrates quite rightly on the 6 mile radius from Charing Cross station. Outside of this its a main road map only, but it does have seperate in depth sections for the airports which it says on the front so I'm not sure how the other reviewer missed it. Its no more difficult to use than a normal map as thats exactly what it is. I've found it very useful the only thing I have to mention is I had to get 2 as the first ones pages were cut too close to the perferations so lots of pages were off the binder.The new one is fine and after 6 months of use is definately worn in but not falling apart by a long shot.
What a great book/map of greater London. It will be my go to travel guide from now on. It shows everything you can possibly think of (tube stops, parks, businesses, historic sites). It arrived quickly. If you want to buy one London spiral bound map book, this is it!
