Great location, great host, great time. Don't get street noise as it's an internal appartment rather than on the street side of the building. Short walk to Prado, Reina Sophia, Retiro Park, Rastro Sunday market, Anton Martin food market, and loads of fab cafes, bars and restaurants in the area. We treated ourselves to an Uber back to the airport, took about 30 mins even with Monday morning traffic. Highly recommended.
