I spent 10 nights at Mariana's place during a work/vacation trip to Buenos Aires. The apartment was perfect for me: located in the heart of the Recoleta - one of the best barrios of Buenos Aires, full of restaurants, walkable, safe, central -, clean, air conditioning functioning well, spacious bathroom, good bed, laptop space, and a balcony on the 6th work that was perfect for glass of wine before heading out for dinner. Communication was great, check-in and check-out smooth. I highly recommend staying at Mariana's place in Recoleta.
