We enjoyed our time at Levy's flat. It has a fantastic location close to both Copacabana and Ipanema beaches as well as local amenities. The rest of the city can be easily reached by a nearby bus stop. The area felt very safe to us.
Levy himself was very chatty and very helpful - he greeted us at the apartment, helped us with taxis, showed us round the neighbourhood and was always available: a great host.
Levy mentioned he'd been having a few problems with his cleaner and we did find the apartment a little less clean than expected, but this didn't greatly detract from an otherwise enjoyable stay.
