We had a great stay at Francisco's apartment. We are a family of 6 (4 kids) and found it to be extremely comfortable and clean. The location was great for us as there are shops nearby and the metro station is about a 10 minutes away, meaning it's only 30 minutes from the centere of Madrid. Franciso was very fast at answering our messages and booked us a taxi from the airport, which cost EUR 40. All in all it was a great experience and highly recommendable.
