We travel to Chile every year and this is the first apartment we've found that doesn't feel like a soulless white box a consultant would stay in for 3 nights before never returning.
The host, Alejandro, is very nice and proactive. For example, he noted his balcony didn't have any netting when he saw we were bringing a 2 year old. While we were there a minor issue popped up with one of the bathrooms and he had a plumber over in less than half a day.
The apartment is sizable and has a lot of amenities you won't typically find in Santiago, like a washer AND dryer, and a dishwasher. The kitchen is big and open, also rare for Chile, and the master bathroom is super high end with a great shower. There is a large terrace with beautiful views of trees and mountains. There are tons of towels and it has a well stocked kitchen. The only thing to note is that the AC is only in the main living room, so the bedrooms can get hot, but multiple fans are in place to help.
11/10 would recommend!
