A smallish, nice and clean apartment in a high-rise building in the center of Santiago. It has no airconditioning (if you are used to it) but it has perfectly reasonable temperature even when we stayed there in the summer. Everything was clean and there were basic utensils for cooking and a small stove. Victoria and her sister helped us with every question we had and I fully recommend it.
The only minor surprise was that the marker for the Airbnb location is a bit further away from where we lived. The place I stayed in is closer to the intersection of Zenteno and Tarapacá. There is great public transport in the city but take note just in case you want to live really close to a specific location!
