Sure, bus transportation is great, and it is a good idea to explore areas beyond Madrid. It is. however, like telling someone to get their butt out of New York and go see the splendors of Saratoga Springs. The huge, loud, moving, shaking, busy (and sometimes unsafe) city is what it is, and Madrid should not be missed! I have to say, as someone who has lived in Madrid and visited often for over 25 years, it GROWS on you. You get used to the noise, the hassles, and learn to find the pleasures. And then, too, you hop on a bus (in my case, a plane!!) and get up to Galicia and enjoy the rural pleasures all the more, having been sated in urbania.
