Highly detailed with many insets, laminated, easy to fold, portable and legible. This is a must for anyone travelling to Buenos Aires for the first time. The maps you get in guidebooks cannot compare. I found it especially useful in booking hotels- I almost booked one in Villa Crespo without truly appreciating how far it is from both the Centro and even Palermo. The entire series is especially handy for travellers who tend to walk or use transit while visiting a new city. Sure, a little pricey, but it pays for itself with the advanced knowlege you get while planning your itinerary.
