You can look long their famous "Bono" metro subscription / bus to get around town ... it is actually the Abono Touristico which comes in several versions elsewhere and not even at that price. .. so at checkout you will have the stupid air qques minutes with your super "Bono" revised on the plane before arriving (especially when you have no concept of Spanish)! Frankly, the little Smart amateurs ...
Another example: they can send you to the other side of town in an alley where there are be-called super restaurants to suit all tastes ... and after 1 hour walk and metro at night, we landed in a corner where there's two shops, one off price of contemporary cuisine, and the other Asian cuisine, closed ... Impeccable small Futé.
In short it is "precise" that can multiply examples, but short examples are worth a thousand words and it illustrates perfectly why I recommend this guide in the idea ...
If I take the trouble to return this writing is that the guide has really disappointed us and worst served. Afterwards I'd be glad to have been warned when buying: guides for Madrid y 'has a fair amount ... for you to test another! Or if my comment makes you want ... why not this one !!
A word ... a great journey !!!
