It is enjoyable to live in this apartment, as I have done for a fortnight. Also, its value is very high compared to what you pay for it: first world standard by all accounts.
If you are extremely noise sensitive like me, Santiago accommodations, and also this one, in general, pose problems: This apartment is nicely located "high up" on the 13th floor at the edge of the "Italian district" of small houses. And yet its orientation may be said to be "on the wrong (western) side" of the condominium building it is part of: on the right hand side (of the terrace) it is facing two huge apartment complexes, overarching it, and fortunately not yet inhabited (they are building another one behind those at the moment); also it is facing a busy noisy street on the left-hand side of the terrace. On the back side of the condominium -- where the pool is located on the panoramic 7th floor, facing the mountains towards the east and the Italian district of small houses -- there would be much less traffic noise. Also, it is (IMHO but maybe not for you ;-) tiny (approx. 5 m x 5 m) and a studio; so that one hears a click every time when the (rather silent) compressor of the fridge starts. If you are less noise sensitive than me this may be no concern for you though. And there are no good alternatives in Santiago anyway, as this city tends to be quite noisy due to old buses and driver's temperaments etc.
The apartment is not really central. Yet the city center is easy to be reached by 5 Metro stops. So you should learn to use the Metro (get the bip! card for 1550 Pesos and ride for about 720 Pesos, depending on the time of day), but this is no big issue.
The pool is nice and often empty; I had great panoramic swims for over half an hour alone there. I believe it is only open during summer time (until March 20th but I may be mistaken) from 9-20; excluding Mondays (where all pools in Chile condos seem to be closed).
There are also free bikes you can borrow for free up to 3 days; and food inside the very building; a good lider expresswithin very convenient walkind distance away.
Karen and her partner were extremely responsive and they were even offering me their bike and an extra parking space during my (prolonged) last day of stay.
All things considered, the value for money was super-excellent.
