Kristian's place is wonderful, and I would highly recommend it for anyone wishing to visit Madrid. The location is centrally located and close to the Plaza Mayor, safe (which I appreciate as a solo female traveler), clean, and beautifully decorated. I also love that both the living room and bedroom have balconies that open, allowing a nice breeze, and view of the plaza in front of the building.
While I didn't meet Kristian, his communication through email was great, and he provided me with lots of recommendations and tips for the area. In addition, he was also very clear with how to use the "self check-in," and messaged me that day to make sure I made it in ok.
The only thing I would let guests be aware of, is that Kristian's place is in a historic European building. While immensely charming, they typically have their elevators up one flight of stairs. This normally isn't a problem, but with a large suitcase (like in my case) was a bit of a challenge. Other than that, everything was perfect!!
Thank you so much again Kristian!
