We arrived just before midnight and the concierge on the late shift did not have our key, though Carlos left it for us earlier that day. It caused us to have to wait 2 hours to get into the apartment - using the WIFI from a local bar to WhatsApp Carlos - he replied immediately, which was so nice since it was so late in the evening. He called and solved our issue though when we arrived at the apartment, it was not as the picture depicted. We specifically wanted the white couch apartment and we instead stayed in the one with a black couch. Not a huge deal but I would have liked to have known upfront. This apartment was conveniently located to Los Leones subway station, LOTS of delicious restaurants (Try Giratorio the spinning restaurant & California Cantina) and lots of shopping. Everything is in walking distance and the view from the terrace is a beautiful scene of the Andes mountains. The space was fine for two people and fairly clean... Our biggest complaint: THE INTERNET WAS SO SLOW. It only allowed one of us on at a time and timed out constantly. Carlos advised us to reset the router but since we switched units, this was not possible and we had to wait a few days. Despite the reset the internet was not ideal for anyone trying to work. If I had to do it over again, I would stay in Nueva Providencia but I would probably find another apartment as this was our 2nd visit to Santiago and had great hosts that picked us up from the airport, helped us around and left a juice in the fridge which was a nice touch. Lastly, we had a family matter which caused our trip to be cut short and Carlos refunded half of the remaining time which was fair and we appreciated his flexibility.
