We spent two very enjoyable weeks in Vivi's and Gaston's apartment. It is in a good location - safe, lots of restaurants (and probably the best heladería in BA) nearby - and the apartment is, as the pictures show, quite light and comfortable. Vivi uses Karina, a local logistics person, to handle checking in/out and providing local help, and she is incredibly helpful. Karina is super-responsive and provided all sorts of suggestions, and best of all for me, lined up a wonderful Spanish teacher who visited each day to further my conversational ability. There is an excellent, inexpensive gym - "OnFit" - a block away, which fit my needs better than the gym in the apartment bldg. The walk to the subway lines is about 12 minutes to Red line and 25 to Green line. The only suggestion I'd have is to replace the seat cushions in the chairs and sofa. I definitely recommend Vivi's and Gaston's apartment.
