Cecilia's place is centrally located and has all the amenities you could want. Though we did not meet in person, Cecilia was in constant communication and the check in and out process was seamless. Cecilia and her husband were very understanding and accommodating to our late and early check in and check out. She also provided a bunch of information about what to do and eat locally. The apartment is within walking distance to most of the attractions in Buenos Aires and right outside a subway station. I would definitely stay with Cecilia if we are every in Buenos Aires again!
