I was in Madrid a couple of days with my sister. Moises's flat is perfect to to explore the less touristy part of the town. The neighborhood is charming with its small atelier, bars and restaurant.
the Moises and Cristina's flat is very pretty, with its retro style, very clean and bright and the owners are really nice people.
They've left us plenty of privacy, our room had no doors, but it was not a problem.
Definitely i'll go back to the Moises's flat when I'll return to Madrid, especially if cristina cook another of his tasty cakes.
