Sweet & Sour.
The sweet part: above all other consideration, Atlantica 5 - Star is a penthouse perfectly located at the right center of Copacabana. Sunrise from there is just priceless. As it is all the beach show & sports life going on there. The neighborhood is safe and full of different options. The air condition system - something essential in a city like Rio de Janeiro - worked perfectly. And the guide that the owner recommends there (named Peter Hult) was very sympathetic.
The sour part: my expectative was far far away of the reality I find there. Nobody was waiting to deliver us in hand the keys (the house keeper did) and give us the introductory explanations; the furnitures that appear at some of the photos aren't the same that the ones that are at the apartment (i.e. the ones at the apartment are not white); the jacuzzi wasn't working well (no hot water), the hot / cold system in the showers wasn't working perfectly, and the house was completely empty when we arrived there (not even a single bottle of water) and dirty with sand probably coming from the beach.
Clearly is not a lived house and its use is just for rental.
