We spent 10 days in Rio with a friend and we totally loved our journey in Lucas place. Botafogo is a wonderful district, the apartment is very well located, close to shops, bars, restaurants, metro, and we felt safe even in the night (but still be carefull, it's RJ ;)
Lucas is very kind and helpful if you need informations about the city. Plus the place is very cosy, we totally felt at home !
the only thing i regret, is that i'm afraid it won't be available when i'll come back to Rio ;)
PS : i skip the view to preserve the surprise !
