I have actually stayed in Cabello Square two times -- during both of my trips to Buenos Aires; first back in October of 2007, and again earlier this month. Both times were about 10 days, and I certainly would not have returned if it was not a great place. Management is always available and is incredibly helpful and responsive. The apartments themselves (I've stayed in two of them now) are comfortable and clean. The WiFi connection was very important for me, and it worked beautifully - quite speedy. The rooftop pool was a definite plus, and I used that whenever the weather was nice. Also, the area is great. It is quiet at night, but you only have to walk a few blocks or a take a short cab to some of my favorite night-time spots in BA. It's also only about 5 blocks from the subway on Santa Fe, one of the major streets in BA, which is great for getting around during the day. Like I said, both my stays at Cabello Square were relatively short, but I would definitely recommend the place for long-term stays as well. I'll definitely keep going back there.
