Brilliant stay at Copacabana! Large, bright, clean. I don’t even know how many guests it could fit. We were 3 and we had totally enough space and all the necessary stuff for a comfortable stay. The apartment is in a few steps from Copacabana beach and 5-7 minutes by foot from Ipanema beach so you are in the heart of this melting pot. As for the safety: the apartment is an absolutely safe place to stay. The neighbourhood is as safe as it can be in a touristic area of Rio. Yes, keep an eye on your belongings, don’t be fool and you’ll be ok. Josy and her assistant are very friendly and they will help you with any issues you’ll have.
PS: There’s a cafe named Farro downstairs - highly recommended!
