Olguita and Willy are a sweet couple that live very close to the airport. There's a bit of a language barrier, so knowing some Spanish goes a long way.
Basically, this is a great place to stay if you want to be close to the airport and want to save money. It's a bit pricey for what you get compared to other private bedrooms in Santiago, but there aren't many options this close to the airport. It's a 5 minute, 7000 peso cab ride to the airport. From the airport, try to grab a transvip shared shuttle.
If you're trying to visit Santiago, I think this location is far from the sites, restaurants, etc. It's basically the suburbs.
