Diogo is such a friendly easy going guy. He's really knowledgeable about Madrid, all you have to do is ask! He provided us with two "tourist" books created by locals of the Malasaña neighborhood to get a more authentic trip. The apartment is clean, with a modern bathroom, the kitchen is limited with regards cooking your own meal however most locals eat out as a time to socialize so full kitchens are not really necessary. Overall I would totally recommend Diogo's apartment.
