This is a very convenient location for public transport, shopping, access to downtown, and the parks by the river. The host allowed me to come in earlier which, after a long flight, was really helpful. From the airport on pubic transportation it is easily accessible.
The WIFI worked very well, plenty of hot water, and all the basics for cooking.
There was 24 hour security desk. I felt safe.
The view from the apartment is spectacular and very urban Santiago with parks. The host responded to little problems promptly.
Given the central location of the apartment, it is a noisy one. As I come from a city , I did not mind at all.
