It's a nice place in a beautiful location.
The good:
Easy check in, cute place, clean sheets, towels, well stocked kitchen, etc. And Providencia is a lovely neighborhood that feels incredibly safe during the day and has a lot of nice cafes, restaurants, parks, you name it. Also within a ten minute walk of essentially all the embassies, if you need their services.
The water pressure and temp are excellent. Internet was fast, although I didn't actually do a speed test and mostly I used it for video streaming and videochat with friends.
The bad:
Not much bad about it.
My two small gripes are that cleaning is definitely cursory- for example, I found a bunch of recyclable trash in a cabinet on my first day there, which indicates to me nobody ever looks in those cabinets.
The apartment is a bit dark- there are lights but because the walls are dark it can seem like it has a lot if shadows even with all the lights on.
