We had such a great time staying in Delfina's apartment in San Telmo! The apartment is spacious, light and has everything you need for a stay in Buenos Aires. The neighborhood was great, central and with many nice shops and cafes nearby. Delfina is staying abroad, so her mother Beatrice was our contact and helped us a great deal. She is very nice, speaks great english and communication was no problem. She came by the apartment to fix the washing machine, and gave us tips about the city too. The hot water in the bathroom is a little difficult and the air condition in the living room didn't work, but that's just minor stuff (and I think Beatrice intend to fix the aircon). We had a wonderful christmas vacation in this perfect apartment! I can absolutely recommend staying here to anyone who are going to Buenos Aires.
