Kristian was a great host and the apartment was perfect. He met us at the apartment even though he was just arriving in from France. He checked in on us a couple of times and he gave me a prompt reply when I asked him for some last minute restaurant advice. The apartment is a 5 minute walk to Plaza Mayor and less than 10 to the Sol metro. Tons of restaurants and bars and truly the heart of Madrid.
The beds were comfortable and excellent AC and water pressure. The TV didn't have English channels but this was not a problem for us, he just hooked up an HDMI cable and streamed US channels. I wouldn't hesitate to book the apartment again.
