I cannot recommend Cristina's place enough. Cristina's place was very clean and well maintained with all of the necessary amenities (the washer and dryer certainly came in handy). Likewise, the apartment was much more spacious than the photos make it seem. This place is also in an amazing neighborhood (La Latina) full of epic clubs, bars, and restaurants and a short metro ride away from many tourist sites. I plan on returning to Madrid quite soon and will definitely book Cristina's place again if it is available.
