Real Madrid Football, Madrid
If you like "futbol", "football", "soccer" or whatever you want to call it, and happen to be in Madrid during any match of Real Madrid don't miss it. It may be a little expensive but is totally worth it.
You may find it difficult to find tickets on the counter or by phone, but resellers are all around just about one hour before the game... as the game time nears, prices go down so you can try to play a little bit with that..
For sport lovers this something worth visiting!
It is huge legendary stadium located in about 20 minutes away(by metro) from Sol. Metro station have the same name as the stadium.
Tickets are hard to get from official ways, because they have pretty strange system(almost 90% of the tickets are sold to members of the fanclub and the prices are much lower for members).
But there are big black markets in the front of the stadium. By bargaining you can get tickets for reasonable price, we get tickets to normal spanish league game for 35€(original price was 25€). It was a good deal for both of us, because I can't get those tickets for 25€ not being a member. For me the tickets in official way would be 40€.
Real Madrid's house.
Take your time and visit this beautiful stadium of the historic football club.
Beware, If you can't handle smoking they alow it in the stadium. The guy next to me must of smoked a pack of cigerettes during the game. It was still fun to be there.
The line for the Football museum was very long, much much longer than the line to get tickets. Make sure to go early if you want to get in.
Do a tour of the Estadio Bernabeu for 9 euros. I went during season adn got to see the entire Real Madrid team training- heaven!
