The apartment is awesome with a great view over Plaza Baquedano (aka Plaza Italia, aka Plaza Dignidad). They have a saying in Santiago about Plaza Italia para arrriba (the rich part) and Plaza Italia para abajo (the neglected part). This apartment is right in the center of action in Santiago, right next to the Metro, right next to Bella Vista, Lastarria and GAM.
If you want to stay somewhere that looks and feels like the US stay in Las Condes. If you want the real Santiago experience, including the poverty and hardship, stay in Victoria or Franklin. If you want to explore all parts of Santiago, this apartment is perfect.
The apartment is a little run down (could use a fresh coat of paint and some minor improvements) but nothing that had a negative effect on our stay.
