We are longtime Airbnb guests, and Patricia and Carlos are truly the kindest and most accommodating hosts. First, they were amazing communicators. We used a WhatsApp group, and they constantly monitored it. We felt in close communication throughout our stay. In addition, over and over, they provide extra attention and accommodation: help with electrical adaptors, making sure our linens were laundered, and letting us stay additional hours when our flight home was canceled last minute. Patricia and Carlos are friendly, well-traveled, interesting, and willing to share their knowledge of all things Rio. They are simply the best.
Oh, also, the place is absolutely amazing! In terms of location, it's just a few blocks from Copacabana Beach, right across the street from the Metro, and near excellent restaurants and nightlife. You certainly won't need a car. And the accommodations themselves are great: airy, high ceilings, comfortable beds, AC, a more than sufficient kitchen, a small pool and patio, and a ping pong table. All of this was as advertised, though actually even better than expected (and our expectations were high). You will find no better base of operations in Rio.
