In a great location for visiting Madrid. Everything is walkable from here. The apartment was perfectly situated for enjoying the restaurants, museums and sights of the city. The Opera metro stop is a short walk away, so simply ask what is the best way from the airport to Opera station, and you'll be set. (Because of single tracking on the main train line during our visit, we combined bus and train for our trip.) The tapa market nearby is great, as was the coffee shop around the corner.
