We wanted a book that would be easy to use, informative and handy to put in a pocket or bag when travelling around. The AA Essential Guide fulfils all that. The Top Ten gives you a great overview of what to see in the city, the suggested walks and itineries help to formulate plans of how to structure your day and the "Where to Eat and Drink" section provides plenty of choices to rest your aching legs as do the pages on Turkish Bath Etiquette! Our one criticism would be the maps. In the densely packed streets of Istanbul we found that we often needed to refer to a more detailed map than the ones provided in the guide which were, at best, not very user-friendly and, at worst, rather mis-leading. However, that aside this is a great guide book to a great city.
