The experience was perfect. We didn't meet Valeria but she was very kind. The apartment size was perfect for 4 adults.
It is 10 minutes away from the metro, but taxis pass in front of the appartment all the time. It is placed in a really good spot of the city: in front of the "Lagoa", really close to Copacabana, Leblon and Ipanema, and not far from Santa Teresa, Lapa ...).
If I have the opportunity to come back to Rio I will try to stay in this wonderful appartment, I strongly recommend it.
