The apartment is located in the best possible area in Santiago. I'm from Chile but I was traveling with a Taiwanese friend. The location allowed us to walk to, or take a short metro ride, to the old, historic city center, Bellavista, the bohemian neighborhood and Providencia, a business and shopping district. We walked to Cerro Santa Lucia and Cerro San Cristobal.
Being located in such a convenient place did bring one small problem. The apartment can be noisy at night. For me, it wasn't a problem, but for my friend, who's more sensitive to noises, was a bit of an issue.
Anabella was very hands-off. But when I encounter a small problem with the hot water and reported it. She fixed the problem immediately! Very quick response.
The place has a big terrace with a great view. We had breakfast and dinner almost every day outside in the terrace.
It does not have A.C. But, because the temperature goes down at night and Santiago has a very dry weather, most places don't have A.C. However, I do think they should provide a small fan.
It's truly a fantastic place, except for light sleepers
