Great apartment in an amazing location - just a few minutes walk from the very busy Plaza Major or the more chilled out Plaza de Santa Ana. Lots of bars, restaurants and shops in the immediate vicinity - if you're going to explore Madrid for the weekend you couldn't chose a better place.
A very short walk from the Tirso De Molina Metro station, which is an easy and cheap way to get to/from the airport.
Sergio is a fantastic host - even helping us to find the apartment (the google maps and apple maps directions from the AirBnB app are not quite correct). Apartment clean, comfortable, well equipped and in a great location for a spot of people watching from the balcony.
Gracias Sergio!
