The apartment is in a good location, a short walk from Copacabana and Ipanema beaches and the Metro that will take you to other parts of the city. It is next to a favela, but I had no problems and never felt unsafe at any time, day or night. The apartment is quite basic but had everything I needed as a solo traveller, and Onayr is a helpful host. It was a relatively expensive AirBnB stay for me, but I was there during Carnival and left it late to book.
