This is a great place while staying in Madrid - nice and clean apartment and less than a 5 min walk to Puerto del Sol, Plaza Mayor and some of the best restaurants for tapas! We very much enjoyed our stay at Kristian’s place. The apartment had all amenities we needed and as mentioned prior close to everything in the city. We did all walking and never needed any public transportation when we arrived. Kristian with incredibly responsive and each time we spoke he gave some great recommendations on what to see and some of his favorite places to eat. The check in instructions were very clear and detailed; we had no problem getting into the building.
