It was a great experience. Even though I didn't have the chance to meet Livia in person, she was bet helpful before, during and even after our arrival. Her neighbor, Cristina, who helped with the check-in, is the sweetest person.
The apartment is in a very convenient location, 3 minutes walk within a metro station and with many bus stops nearby. It is also very clean, with cooking supplies, and almost anything one would need.
