Welcome. The best deal is AA FLT#94 @ $95 going and $135 return. Once you get to MAD and clear customs go down the hall and get the metro to the city. I stayed in Arguelles which is kind of mid-town about 4 stops from Sol which is the heart of the city. Lots of shopping and walking. El Corte' Ingles (a la Macys) is across the street. MAD is huge 3 mil people so with any big city..
