Great location!
Stayed there to attend Atlético game. 10 minute walk to stadium. Easy access from the highway. Free underground parking. Las Mesas metro station only 5 minutes away. Gives easy access to the tourist sights in central Madrid. Took line 7 to line 5 and got off at Opera, which is less than 5 minutes to Royal Palace. Took about 30-35 minutes from the apartment to get to Opera station.
