Lilian is a very nice person and arranged for us that we could enter the flat even when she was away. When she arrived, she helped us with some tips on what to see and where to go in Rio. She was also very kind to make us a cofee in the morning and we also got from her some local candies (or maybe these were nuts?).
The place is conveniently located, near Copacabana and Ipanema beaches, very close to one of the entrances to Metro General Osorio station, so it's easy to explore Rio from there. Do not expect any great views from the window - just a similar building on the other side of the street. The neighbourhood is nice, apartment and the whole building is clean and well maintained.
We really felt at home there.
