Kristian's place was perfect for my husband and I's stay in Madrid. We were met promptly for check-in by his colleague, Ivan, and check out was a breeze. The location was walking distance to plenty of cafes and restaurants as well as Plaza Mayor, Puerta del Sol and Mercado de San Miguel! The stairs up should be no issue because there is a lift, but honestly after all the delicious food we ate, we needed the extra steps. Thanks for a great stay. Cheers!
