This apartment is awesome. It is a nice sized apartment with all the amenities you need for a short stay in Madrid. It is located in the perfect location. Walking distance to all the must see spots in Madrid (e.g. Museo Del Prado, Plaza Mayor, Retiro Park, etc.). My wife and I stayed here for a few nights and it was perfect. Helena was also readily available when needed to communicate questions/concerns. The only thing I would say is if you are traveling from the US, do not forget to bring an outlet converter. I highly recommend Helena's place.
