Bored in Madrid?
Remember, Madrid is the city of the "two B's": banks and bars everywhere you go. How can you get bored with so many terraces, bars, clubs and wonderfully dressed spanish women around?
Madrileños are known to be open people. Even when your knowledge of the Spanish language is limited, you won't find it hard to get a conversation going.
Go and see an Original Language movie (V.O., look in section in El Pais or other newspaper) in one of the many movie theatres in the city centre.
Go to the El Retiro and have some cañas at the terraces.
Go to the special summer-terraces at "los bulevares" round 11 o'clock at night and have yourselve some "cuba libres" while admiring the spanish women.
Go to the Plaza Mayor and take some (very expensive) Jamón Ibérico with some red wine or beer. Visit the 'old Madrid centre' like Las Vistillas, or the streets around Plaza Mayor.
Or go to Plaza Santa Ana at night (Cervecería Alemana). You'll probably find other foreign people in a similar situation as you.
