The location of the building is central to many of the important areas however i will say, I rarely stayed within a few minutes except to go to the string of restaurants beside the building or running along the park. It's the perfect spot though to always be around a 15-20min walk to the main areas like Lastarria, Bella Vista, Barrio Italia, Sky Costanera, Bella Artes, etc...
The building itself is very basic but functions well. No real amenities but didn't need that.
Apartment was as described however it was difficult keeping a constant temperature in the shower and little less pressure than I'd like but I've been in worse.
Andrea was communicative and helpful throughout the stay.
