This is an excellent value and well worth it.
The location is the kind of place you want — it straddles a couple of busy areas, but isn't smack dab in the center of either of them, which means you won't suffer from noise on the street. I really loved the nearby Plaza General San Martín, a lovely park with beautiful flowering trees where you can take a stroll or people-watch, and there was not a single night when I didn't go to the Rapa Nui chocolate shop to get a chocolada or amazing chocolate ice cream before heading to the apartment for the evening.
The space itself: clean and airy, on a high floor so a nice city view. There's plenty of light, but the orientation of the windows and the lovely breeze meant it never got hot.
The host is the wonderful kind of person that you might imagine is rare to find in a big city. I was quite touched by his sincere kindness.
You will not be disappointed here. Book it immediately.
