My mother and I stayed at the apartment, and it was overall very good. The location was excellent both in terms of shops and restaurants nearby, and also being right next to a charming square with a cute church that would chime every hour - usually letting me know how long I had slept, and sleep well we did. We did however have trouble understanding the washing machine, the TV did not work, and other appliances were fickle at times. Also, the showers were interesting in that they seemed designed to land outside the shower area (particular the shower stall). But these were all minor, and communication with the host was good, so I would recommend the place, and would consider staying again on my next visit to Madrid.
