Stayed in the apartment for three months while working at an internship in the area. The apartment was absolutely lovely and matched perfectly the pictures. The entire apartment with its tile and metal kitchen surfaces is easy to keep clean and I loved it as a longer-stay traveller! Aline was super responsive to all communication and was very friendly. The location for the apartment is great, only a stone's throwaway from a lot of good bars and restaurants, and then close to a bike station and subway to travel to other parts of the city. I definitely did not mind paying for the electricity out of pocket and that I definitely was saving a few bucks per day for it (I used about ~$15 USD per month).
Would easily recommend to others, and book again if I ever find myself back in RJ.
