The vibe in Madrid is unlike other European cities I've visited -- lively and energetic from arrival at Atocha (main train/bus hub) and getting on the right bus (wrong direction though) to the apartment rented in the old section of Madrid.
When I had an uneasy feeling that perhaps I had been on the bus too long without reaching the plaza that was supposed to be 6 minutes away, I pulled out my notes on the address and asked a woman near me if I was headed in that direction.
She didn't speak English, as no one else on the bus seemed to, but my notes were handed around and everyone had loud overlapping discussions then appeared to be in agreement that I was headed in the wrong direction and pushed me and my luggage out the door at the next exit with charades and Spanish directions to cross the street and get the same # bus but in the other direction.
Made it to the apartment, dropped the luggage and headed out to enjoy the sunset and the nightly paseo of the local Madrillenos.
Just before sunset, the locals will stroll the streets with their families, greeting neighbors, some until after midnight! Couldn't figure out how they could be such night owls until the next day when many shops and businesses closed for the afternoon siesta.
