Carolina's apartment is amazingly well located in Las Condes, around 5 minutes walking to the closest underground station and bus stops. A main avenue is located just 200m from the building entrance if a private car or taxi is needed. Carolina replied to my messages almost immediately, and she was always willing to fix any issue in the apartment. Concerning the space, it is ample (considering Santiago standards as an overcrowded city), very clean, and comfortable. You can have a good night's sleep, and in summer (the time that I stayed there) it is not hot at all, actually very fresh. I would certainly recommend this place.
