The apartment is as described. You have a nice 17th floor balcony that looks toward the east and an excellent view of the Sky Costanera building that has a 360° viewing platform on the 61st floor.
The location is very near the Salvador metro station and on the same block is a restaurant called Oculto Beergarden which we didn’t discover until late on our last night. Even so, at 2300, on a weeknight, it was packed with happy customers.
I would recommend this Airbnb to anyone spending time in Santiago. German provided excellent check-in instructions and we had no problems with communication.
