Natália was a great host. She met me at the apartment and described everything I needed to know about the studio and the area.
The apartment is nice and has everything you need. Supermarkets, the main metro station, buses, restaurants are all nearby. It's also a 10 minute walk to all 3 popular beaches in the area which is perfect. I spent 4 weeks there and it began to feel like home.
Note that you need to be careful at night time and this goes for anywhere in Rio. Ipanema is definitely safer than most areas but it's still recommended to take Ubers when traveling alone at night time.
