Luiz was very responsive while we were working out the details for our trip. The location was convenient enough for getting around town: 10 minute walk to the metro, 25 minute walk to Sugar Loaf, we took more cabs than normal for the easiest transporation (most local trips were 15-20 R$) and I walked the flip flops off my fiancee (which was relatively straight forward with a map). The room was very comfortable (A/C worked great, much needed in the heat) and the bathroom clean. The building complex has a fence and 24/7 doorman. We felt very safe here and throughout the Botafogo area. We loved eating breakfast with Luiz and hearing his stories and recommendations about Rio. We took a cab to and from the airport. We lucked out with a metered cab one way (45 R$) and Luiz called us a cab the other way with a fixed price (same 45R$) which was very helpful as it took us 1.5 hours in the evening traffic (1700-1830). Luiz has great restaurant recommendations.
Enjoy your stay!
