Great location - walking distance to the red line metro makes for easy access to other parts of the city. The unit itself is really nice and the staff at the front desk are very helpful. The surrounding neighborhood feels very safe. The property owner was also great about communication as my flight into Santiago landed super early in the morning. I would definitely recommend staying here.
My only negatives were during the day the area and building were noisy (the noise from the hall especially), and the fitness center leaves a lot to be desired as it only has lighter weights and some cardio equipment. But these are only minor inconveniences, especially if you are looking for a home base while exploring the city.
