Leny is such a wonderful and welcoming person. She literally welcomed me to her home with open arms! It really felt like I was staying at my aunts house. She makes sure you have everything you need during your stay and is ready to go above and beyond to accommodate her guests.
Regarding the location, it is in front of the Maracanã stadium and it's metro station, giving you easy access to the rest of the city. The house is in a gated residence with 24h vigilance so I felt very safe arriving even late into the night.
