Pros: Responsive host, flexibility at check-in/out, unit was clean on arrival, awesome quiet location, nice size unit, has air conditioning (in the summer you will want that!). Nice large bed, comfy linens. Building has a roof top pool with a nice view, has parking. There's a very basic gym, it's dated, but at least there's one.
Cons: Older unit, some things could use an update such as torn curtains and the couch which is not comfortable at all. Kitchen has very little for you to cook, no dish drain, no frying pan or spatula if you want to simply fry an egg for example at breakfast time. Chile does not have coffee culture so there's no coffee maker, but you can boil water for instant coffee, obviously not the same. Bring your own soap, shampoo, etc....might be a cultural thing but those were not provided either.
