Cute, comfortable and very central apartment. If you're transiting in Madrid from other Spanish cities via train, this is probably your best option since it's a mere 2 min walk from the Atocha Renfe station. The metro is nearby too, but you can really just go anywhere by walking - the Prado Museum, Puerta de Sol and tons of great food options are all but a leisurely walk away. Carmen was a lovely host too!
