I stayed in David's apartment for 2 months and extended it for another month. We had some small issues with the internet and water at first, but David was extremely responsive and helped resolve these immediately. David is also a great host, and we shared an interest in mountaineering. He recommended me a bunch of great hikes and mountains.
The apartment itself is great, it's large and spacious with great furniture and decor. The location was set in a quiet neighborhood but close to the metro and bus stops. There are tons of great restaurants around.
I highly recommend his apartment if you plan on visiting in Chile. I know I will be contacting him again next time I come back.
