This map seems to be geared towards tourists. If you'll only be traveling within the toursit areas of the historic downtown, Miraflores, and Barranco then this is a great map for you. However if you wish to visit areas that most toursits skip like suburbs of San Borja or Chorrillos then you my friend are out of luck. Many useful places, for example the US Embassy, are covered by the street index, and a completely useless picture of some of the historic balconies that can be found downtown. The Pacific Ocean even makes an appearance on this map, wasting about 5% of the space, so they can display Barranco. I think they should separate the Lima map from the Central Peru Map so they can show more of the city on the back or change the name to Lima Tourist areas & Central Peru so people know what they're buying. FYI if you want to use the buses in Lima then I highly recommend the map Lima X4 Guia Distrital by the Lima 2000 group. Not sure if Amazon sells it but it can be found at bookstores in Lima. The fold out maps are small which is good so you don't disturb anyone on the bus, easy to read, highly detailed and cover just about all of Lima.
