I've managed to find the location of her apartment. I did a search for that image, and came up with this:

The most interesting part, obviously, is, "In the heart of Las Cañitas neighbourhood, famous for its restaurants, pubs and cafés. The location is excellent (
between calles Baez and Chenaut) close to many interesting touristic points like Palermo Soho, Recoleta and Belgrano. Two blocks from the Polo Arena. Safe during the day and night."
So, googling "Chenaut 1967, buenos aires, capital federal, argentina," which is the address from her domain registration, you get precisely that location.
