Query: Packed full of information and insight

Besides plenty of practical information (hotels, restaurants, etc), this book contains seven suggested walks in St. Petersburg. They range throughout the center of the city, Vasilievsky Island, the Smolny area and the outlying palaces (and full attention is given to five of them rather than just Peterhof and Tsarskoe Selo as in most guidebooks). It also includes a walk in the Hermitage. These walks include good maps. Additionally, this book has excellent sections on the history of the city, customs and various subjects (the "mafia", icons, vodka, etc.) that provide context for your visit. The author is an excellent writer who, although she obviously loves the subject, presents a thorough picture.
