Mariana & Dominic were very communicative, and the place was nice. You could tell they put a lot of effort into wanting guests to enjoy their stay.
Admittedly, it was stressful to get in around 8 or 9 PM and have the code they gave me not work on the door (luckily, Dominic was awake and was able to give me a different one)...but that could've been a once-in-a-blue-moon thing (a cleaner had called in sick that day, so things were a bit off)
There wasn't hand soap nor shampoo (not sure if the listing advertised the latter, but it did the former), and the welcome folder on the table--really detailed and filled with suggestions on places to see in Santiago!--didn't have the right WiFi in it (partially my fault...I really should've just flipped over the router sooner).
It's not the safest area: Dominic told me that a few weeks before, he had seen gang members shooting at each other outside his window (in the same building)
The biggest issue I had was the heat. As many buildings in South America have turned off central heating due to high gas prices, the apartment has a propane-powered heater that will warm up the living room...but unless you want to carry it/the propane tank into the bedroom, it's freezing in there, sometimes even under the covers. One or two portable electric heaters would make such a big difference.
A lot of these issues might have been, like I said, just from a random, chaotic weekend...so it might be worth asking them about the heat and other things before you book the place
