Natalia has a wonderful little apartment in the Recoleta neighbourhood. It's a small apartment, but it's got everything you need. It's located in a safe neighbourhood with quite some bars and restaurants close by. Communication with Natalia was great, although I did not meet her in person. She responded to whatsapp messages within maximal 15 minutes, and was ready to answer all sorts of questions. If I ever return to Buenos Aires, I won't hesitate to book this apartment again.
