Guilherme answered very quick to my last minute (literally) request and I really appreciate that. He left the keys with the doorman so get into the apartment was easy. We communicate without problems. The place is 4-5 blocks from Copacabana beach. Outside a little bit noisy until about midnight, but it didn't bother me. I didn't meet Guilherme in person, but everything was ok. Thanks Guilherme!
