Nene's apartment is in a lovely vintage building with attentive and friendly 24hr doormen. The apartment was as described and matched the photos. There is excellent art and decor in the apartment. The small balcony is nice for a drink or to read on, and the view is incredible. Despite being very small, the kitchen has everything you need to cook simple meals, and was fine for our 6-week stay.
The location is right in the middle of Santiago and close to the markets and historic center of the city. The area is a bit more gritty than some newer neighborhoods, so I think it is best for confident and experienced travelers and people who are comfortable in large cities. That said, we loved the authenticity and ambiance of the apartment.
