Wonderful location, walkable to cool shops, varied restaurants and bars, and also near the metro. Santiago provided useful information before arrival, which helped a lot. Apartment is fairly well equipped for a longer stay and is definitely big enough.
However, the apartment wasn't very clean, neighbours were noisy and uncomfortable beds, but due to the location and the price, it was worth it. Maybe take own towels and earplugs. Plan to eat out or buy paper plates etc.
