The apartment was very clean with modern furnishings. I was greeted at the apartment upon arrival (even though I arrived at 8am!) I had no problems with anything in the apartment and the owner checked in with me a couple of times during my 1 week stay to ensure all was ok.
The location is in a nice part of Copacabana, one block from the beach. There are many restaurants, supermarkets, pharmacies, stores, etc within waking distance. I have stayed in this apartment a number of times over the past few years and would highly recommend it.
