If you are ever traveling to Madrid this is a "must have". The pocket version is small enough to carry in a purse or pocket without being to heavy or too big. The map is INVALUABLE! You can note the places you have visited and write reviews of your travels. This will be a fabulous record of your travels to pass on to future generations or to even use when you return to the city on a future trip. It solves the problem of not being able to remember where you ate and what you ate. I had purchased the one for Washington DC a couple of years ago & I use it each time we go back. The on for Madrid was purchased as a gift for a friend who was studying in the city for a semester. I give the New York City book as gifts for visitors from foreign countries who are visiting our family. They love the gift.
