Kristian is a very friendly host. If we weren't so broke and tired (this was the end of our trip), we would have taken him up on his offer to hang out.
It was nice to have a tv in the room, the bed was comfortable and there was a nice breeze coming in from the window (he also has a fan)
The location was great, we never took the subway since every major attraction was within 5-45min walk.
We recommend Kristian's place to anyone who is thinking of visiting Madrid!
