Matias’ place is a beautiful modern apartment in one of the trendiest parts of town - very easy to get around from and conveniently located next to a huge shopping mall. The beds were comfortable and the space was well decorated - and the view is great. There’s also a in-building laundry and rooftop pool, though it was closed for maintenance during our stay (which was unfortunate since we got some very hot days).
I’d definitely recommend Matias’ place for a stay in Santiago!
