Casa Encendida is an excellent choice! Sandra’s apartment is modern, clean, very well equipped and in an authentic and safe location that makes you feel more like a local than a tourist. Great access to neighbourhood bars, restaurants and shops (love the 24hr Carrefour supermarket around the corner) and Sandra’s information about the history of the area and her favourite drinking and eating houses is brilliant. Easy access to many of the popular tourist options in Madrid and some great walks (or short taxi journey) to most of the others. Atocha Train station is nearby and is a hub for many day trips out of Madrid and the airport. Five nights in Madrid was not enough for us, so I’m guessing we will be back some day - we would have no hesitation in staying at Sandra’s apartment again.
