The apartment is really good. The beds are comfortable, the comforters are really cozy and warm (we needed them in the cold Winter of Buenos Aires...), the air conditioners work well (although there is no unit in the room with two beds) and there was plenty of hot water in the shower and faucets. Although you are not staying in Recoleta (I stayed there in my last visit to BsAs), I felt safe enough at Avenida Corrientes. Ana and her husband were really responsive and truly nice. I recommend this apartment and would stay there again.
