Ana's place is literally 1 block from Copacobana beach. There are 2 supermarkets downstairs that are open between 8 and 10. Ana's place is on top of some local bars and restaurants which means it can be quite busy with people and loud downstairs. Her place is also on the corner of a road which leads up the hill and has a 24hr police presence on the corner of the road. Her place has 24 hr security to let you in.
Her place has 2 double bedrooms and 1 single bedroom. Each has corresponding bath room and the 2 doubles both have air con. The wifi was fast for Brazil and the kitchen had everything needed for breakfast and dinner.
Ana is a great host and was very flexible for us. We arrived about 10pm and she stayed to let us in and gave us some tips for travelling. She then let us check out late (about 6pm) as we had arrived late.
I would recommend this place for groups of people as you are literally next to the beach and about a 15 minute walk to Ipanema. We got taxis/ubers to Lapa and the airport which were quite cheap by western standards.
