Carl's place was the perfect apt my family needed for a week's stay in Madrid. The whole place is just as pictured and very well equipped. The newly installed AC units were lifesavers in this 38C/100F heat. Even though metro line 1 is closed (till Nov2016), catching trains/buses from Sol or Atocha was still quite convenient. Carl as a host, even though he was out of the country was very responsive with any question I had and courteous with every message and always checked in to make sure we were doing ok in the flat. Recommended 100%.
