Is Madrid to big for making real friends?

Madrid offers so much plans to do, but what if we are new in the city and don't have real friends to take a cup of coffee, go for walking or visit the city.
Some people enjoy the loneliness but it is not as easy, If you want inspirations for going out you can look at this posts about "Tapeo guide in Madrid"( Protected content ) and "The best low cost bars in Madrid" ( Protected content ).
So you can start to make plans y yourself or with your new friends.
