My stay at Robert´s apartment was great and I highly recommend staying there. It is very well located, just a block from Santa Fe, on a relatively quiet (for a city) street. I ended up staying longer than I had planned, as I could get to wherever I wanted easily. There is a Subte stop a few blocks away and a fine selection of restaurants within easy walking distance. Robert was very helpful with suggestions, most of which I followed and was pleased with.
