We spent a week the the appartment and we would go back. It is clean and very well situated if you want to be in the Bellavista area. Very easy/safe to walk to the restaurants/bars and to the San cristobal mountain (great for the views but also to exercise/run). It is also very safe with multiple locked doors.
Special mention for the great communications. Quick, friendly and very usefull.
Thanks for the great week!
