We felt at home! The apartment is tastefully decorated and well equipped (large TV, air conditioning, kitchen utensils, etc). It's clear that this is a place where someone can live. I really appreciate that the lock is electronic (we didn't have to use physical keys ever - very convenient!).
The view is truly breathtaking, and the windows are huge, letting you see the mountains and the city. The blackout curtains did a decent job blocking the light, but it wasn't totally dark in the morning. On the bright side (pun intended), if you open all the curtains it's VERY well lit.
The location is ok (pretty centric, really close to public transportation, but it's not the nicest zone of Santiago).
Carlos is a wonderful host - he's kind, helpful, replies messages very quickly, and he even received us at the apartment late in the night.
