My wife and I stayed 4 nights in Eduardo's apartment, which in a luxury building with security guard. Great location: facing the lagoon and near all major tourist attractions (beaches, Christ, etc). Although Eduardo doesn't speak a lot of English, he did his best to communicate everything with me. He prepared an instruction sheet and made sure our names were properly registered at front desk, where all the guards were also very helpful. Overall we had a wonderful experience in Eduardo's place and in Rio.
