Absolutely perfect location. Steps away from great restaurants, bars and museums. The place itself is what an Airbnb experience was always meant to be --- the chance to live life in someone else's shoes, as it's clear that the owner of this place calls this Santiago apartment her home. The terrace overlooking the city and full of greenery was a truly a highlight.
All that said, given the price, some minor fixes are called for. E.g., better water pressure in the shower, black out curtains for the bedroom given how bright it gets in the morning, and a king instead of a queen sized bed.
