Staff was really friendly and flexible! Location was good, really close to the Prado Museum and Parque del Retiro, and a short walk to Plaza Mayor. The neighbourhood was lovely, with narrow streets full of bars and cafés.
The only thing I'd point out is that the walls are paper thin, so if you're after privacy it's not the right place (there was a couple next door and I could hear them taking clearly).
