The apartment was well located, very close to Ipanema Beach (around the corner). It was very clean, nice, remodeled, better than the pictures. It had clean towels, all kitchen accessories, and enough space to walk around. There was always a doorman at the building, it was quiet all the time, perfect to rest at any time. Also, it had a very small laundry area inside the apartment, where all cleaning stuff was packed away, there was also a parasol (so you don't need to rent one at the beach) and a small grid where you can put on your clothes if you want them to get dry. Wifi, tv and kitchen worked well.
I never saw Nereu, he left the keys at the mail box for me. He helped me just enough by whatsapp. I would have liked to find some information of the city in the apartment, maybe a map of Rio de Janeiro or some sort of tourist info, but it's nothing you can't find around.
The subway station is one block away, the bust stop is very close, there's a 24 hour grocery store a couple of blocks away, and many other stores around. Great location.
