My wife and I had a fantastic time at Arno and Igor's place. It was a tastefully-decorated and in a great location full of many shops/restaurants and 3 blocks away from Ipanema. Communication was excellent (!!) with messages being returned often within the hour. Unfortunately the toilet water was cut-off in our part of Rio for 1 day, but they gave us clear directions of what to do and how to manage around this. They also gave us a useful tip for a Rio tour that allowed us to see most major sites in 1 day. They took time to answer all questions and even allowed us to check out late on the last day which was super helpful. All in all, an excellent choice.
