Sergio's place was great! It was exactly how he described it, the views of Christ the Redeemer were great and it was a short easy walk to the beach and subway. Sergio enthusiastically met us early in the morning when we arrived from the airport and gave us all the details on things to do, how to get around, and what the cost of taxis to various locations should be (so we could budget appropriately). He recently started operating a guesthouse and while we were in Rio he hosted two evening socials at his house where we got to meet some of the folks staying at the guesthouse while drinking caipirinhas (Brazil's national alcoholic drink). It was a great vacation and I would totally stay with Sergio again if I'm ever back in Rio.
