I stayed at Delfina's place for 10 dyas as I was in Buenos Aires for work. The apartment corresponds to the pictures and description and is in a good location with a Subte station and lots of shops, cafes and restaurants in walking distance. Delfina wasn't in Buenos Aires, so I never met her, but she responded to all my questions very quickly by e-mail. With the central location comes a bit of noise, but it didn't bother me too much.
