The apartment (and the building itself) is quite new and well furnished, just as in the pictures. It's small but comfortable enough. Kitchenware is basic though -- you are not expected to cook or eat in the apartment too much. The bed is good.
It's well located -- Parque Arauco and Open Kennedy malls are two blocks away and has most of what you could need. The apartment has a 10th floor inside view, where construction work on two huge buildings is just starting out and probably will be active for the remainder of 2022, so expect noise during business hours. It doesn't get too much sunlight, but it's well lit anyway. This is one of the tallest apartment buildings of the zone, so don't miss the spectacular views of Santiago by the rooftop pool.
Overall I'd recommend for short stays and I would come back.
