My parents and me had a wonderful stay in Ana's apartment. It was central so we could reach everything easily by foot or by bike! Her aunt welcomed us warmly and explained a lot about the city+transportationsystem+restaurants, which was a great start in such a beautiful and big city. Everything works perfecly in the apartment: kitchen, bathroom, aircondition (which you need in summer in BA), so we were completly happy with our stay. Also the check in and out times were flexible so that we did not have to wait and could leave whenever we wanted! I can defenetivly recomend to stay in Recoleta with Ana when you are in Buenos Aires!!:-)
