Staying with Kristian was great. When I came he gave me an entire apartment instead of the room I reserved because I had reserved too early and things came up, but instead of cancelling the reservation he gave me a huge free upgrade. Kristian was always there to help, even when I was struggling with my keys and buzzed him in the evening. Kristian gave me a map of Madrid and circled all the places I could go to so that I could enjoy the most of Madrid. The place itself was at an easily findable location from the Sol station, so I had no problem using the metro and cercanias to move to and from the apartment and the rest of Madrid.
