I booked this property spur of the moment. The price was right, location excellent, breakfast ample and superb, the staff congenial (and most spoke passable English, which helped out this linguistically challenged Canadian!). I’m on a budget, like most travellers, so the Centropuerto airport shuttle bus, which drops you off a 5 minute walk from the hotel (2,000, or about $3) at Los Heros, was a bonus. They run every few minutes, so waiting isn’t an issue.
Just a heads up, the hotel has just opened, so they’re still doing work and whatever I may write now may not be the case down the road. I never really noticed any noise, other than some street noise at night. The hot water took a while to flow but (….see above). On the other hand, everything is new and beautiful and sparkling. There’re plenty of dining, drinking and grocery options nearby, and the downtown area is an easy 10-15 minute - I like walking; it was no issue for me. Check out the nearby museo de la memorial y Los derechos humanos - it’s free entry and gives you some insight into modern Chilean history, the military dictatorship, and the disappeared. Sobering stuff. On a happier note, do get into the mountains; they’re not far and wondrous.
As a final observation, I came down with a cold my final days. The staff were super kind, bringing me fresh fruit, pastries, and tea. Awesome people. Family.
