Very nice apartment in a nice area. It was very cold in Buenos Aires and the heating broke down so it was freezing cold in the apartment. But Martina went out of her way to try to fix it. Unfortunately it was only fixed the second day of our two days stay...
Apart from that the sofa bed isn't very comfortable.
For the rest, the apartment is very nice and convenient.
Maybe a bit expensive for what it offers, but I would still recommend it when it is not too cold in Buenos Aires !
