The apartment is really beautiful and was extremely clean! Also very quiet as it is not facing the street. Location is great. About 10 min walk from Nuevos Ministerios metro station. Claudia and her husband Oscar were great hosts. While I did not get a chance to meet Claudia as she was was away, Oscar welcomed me and was really helpful in providing information on the apartment and surrounding areas. I also enjoyed all the amenities provided including very good Colombian coffee! :-) I would certainly love to stay at Claudia's apartment next time I am in Madrid!
