Javier is great at communicating, whether it's through the Air BnB site or via WhatsApp (I got his number before traveling and contacted him this way). The apartment is in a centrally-located area close to many tourist attractions, restaurants and bars. It is also extremely close to a Metro stop and a grocery store (Lider Express). Though we went from November 13-16 during all of the protesting in Santiago, we were still able to sightsee (but more of in Las Condes and Vitacura and not in downtown or Barrio Bellavista), and we never felt in danger (and we had a 4-month baby with us!) where we were staying. The only inconvenience the protesting caused us was that some restaurants and stores closed early, traffic was horrible during the day, and the Metro stations were not functioning with regularity. But since the location is so central, we simply walked to most places during the day and ate at the open restaurants at night (and there were a bunch within a block radius). All in all, we had a great time! Javier was very helpful in helping us know where to go and where to stay away from - and we knew if we had any questions, we could simply contact him and he would get back to us in minutes.
The apartment itself is very small - but very clean and modern! Especially the kitchen. We loved the balcony and keyless entry system. And there is a rooftop pool that opened on Nov. 15th for the summer that is AMAZING! The views from the rooftop are impressive and it was refreshing to be able to cool off in the heat. My only complaint about the space was the sleeping situation. The bed was a bit bouncy and so I woke up every time my husband moved - then again, I am a light sleeper. Also, even though the apartment is on the 13th floor, it is still noisy from traffic, but hey, Santiago is a huge city so that's expected.
