This place is perfect if you're looking at a short stay in the Copacabana area. The apartment feels secure and the beach is barely two streets away. The apartment is clean and the kitchen has serviceable utensils you can use to cook. The place is a bit small and you'll knock your elbows a few times in the kitchen, but given the location and the accessibility, we (I, my wife and son) were very happy with it.
We never met Andiara, but she responded to every question or request I had... I have no complaints about that either.
