It has been a pleasure to stay in this amazing, little appartment. Not only because it is so cosy and clean, but also because of the friendly owners Karen and Carlos. I felt at home straight away. The bed is really comfortable, there is a Netflix connection in the television and safety is guaranteed thanks to the reception downstairs.
There is no noise whatsoever from neighbours, though you can hear the cars of the avenue closeby (which is almost inevitable in Santiago).
Would definitely stay here again when coming back to Chile :)
