This is the place you seek. Truly. I've stayed in dozens of Airbnbs, and this is absolutely one of my favorites. The location can't be beat: literally meters from the metro, on a semi-pedestrian street connecting to a nice, safe pedestrian street in a nice neighborhood. The view from the large windows is great, and overlooks the metro station plaza and a street with a cafe playing live music in the early evening hours, with the cityscape and mountains behind it. The apartment is well-decorated, with all the comforts you could want. Communication with Roberto was great. 24-hour doorman, and a digital lock, so no key to carry around. It's definitely where I'll want to stay next time I'm in Santiago.
