My husband and I spent 4 nights at Andrés beautiful apartment in Santiago. Andrés was very helpful and extremely communicative. The apartment is well appointed, comfortable, and spotlessly clean. It has amazing nighttime views. It is about a 20 minute drive to the city center and there is very large mall with lots of dining options just a short walk away.
The only thing I would point out is the bathtub might be difficult to get in and out of for someone who has mobility issues.
