Rozio, my mother[-in-law], enjoyed staying at Mauro's place after we had left Buenos Aires already earlier after New Year's Eve. She's been staying for about 2 more weeks at his place. Mauro was very responsive and welcoming. When there was an issue with having hot water, Mauro took care of it as soon as reported. Belgrano is nice residential neighborhood. It is easy to get to Tigre, Palermo, and Recoleta. Would recommend staying at Mauro's place.
