My girlfriend and I had a great time in Madrid staying at Nina's place. We were worried about some of the comments about noise from the restaurant below, but it was not an issue at all for our weekday stay. The Tirso de Molina was a great launching point for visits to the Plaza Mayor, Prado, and Reina Sofia, and a short walk to awesome restaurants in La Latina. At the end of your stay, Atocha station is only a few stops away on the Metro. We would definitely stay here again.
