The apartment is exactly how it is described, Recoleta is beautiful and safe. The location is perfect, a walking distance to the subway (Subte) and bus stops, but also very central if you like walking (which I recommend in Buenos Aires). Sofía was really kind and helpful and communication with her was easy. There's a booklet at the apartment with useful information and tips, prepared by her. As for the check-in, Sofia's mother, Malvita, waited for me though my plane arrived late, and welcomed me with a smile. I hope to go back to Buenos Aires and I'll definitely try to stay at Sofía's place. Muchas gracias, Sofia!
