Stefan's place is great. The center of Santiago's center - that's how would I describe the location. Walking distance to many of Santiago's signature sights, numerous transport options, many shopping spots nearby (both for groceries & other things).
The apartment is very clean and everything is as advertised - perfect for 1 or 2 people.
Stefan is very friendly and went out of his way to help me with certain Santiago lifestyle tips that I had trouble finding on the internet. Communication was always quick and clear.
Highly recommended!
