2 Calle Preciados
Spanish breakfast(first of all ignore the address because that isn't it but the only option that I get)
This small cafe is close to the metro stop Islas Filipinas and is my new favorite breakfast stop - two and a half euros for a cafe con leche, churros and a glass of orange juice.
The address is actually Calle Guzman el Bueno, 127
And there is free wifi!
