Highly recommend Alex’s place! The apartment is located right off Copacabana beach with lots of restaurants nearby as well. The apartment has hot running water, a/c in the bedroom, excellent wifi, and 24 hour security/attendant on-site. Alex is also a really good host that has a very friendly personality and was always more than happy to help with suggestions, directions, etc. I would definitely stay at his place again if I was back in Rio!
