The place is super awesome. Accesible by Renfe Rail Line from MAD Int. Airport. There are trains every 10 -15 mins to Atocha (where you need to go) and you just need to do one train transfer in Chamartin. Many points of interest such as Puerta del Sol, Wanda Metropolitan Stadium and Santiago. Bernabéu stadium are just steps away from the apartment and connected to several metro lines. You can buy food anywhere around almost every hour of the day. In brief, it was awesome to receive check in instructions prior getting there. It was just great.
