The apartment has an excellent location for seeing the city. I have noted several comments about concerns for safety but we never had any concerns during our stay. There are certainly homeless people in the neighborhood but they do not represent a threat. Homelessness is a serious problem in Santiago but is much worse in other parts of town.
The apartment is clean and well maintained. You have all of the basics that you will need. And while the apartment doesn’t have air conditioners, during the hot spells there are fans provided that give excellent service.
Finally, I wanted to mention that I have never had a host who has been more helpful or responsive. If you have concerns or problems an email or call will get them resolved. Sarah is an outstanding host and resource.
