I've stay in JW Marriott hotels when ever possible. This one has excellent and friendly staff and they have made this hotel as nice as they could. Given the limitations of many buildings on Copacabana, many of these rooms only have a window to the interior courtyard/lobby. That was the main downside. Otherwise, everything was excellent. Very comfortable rooms, good sushi at the bar, friendly English-speaking staff. Good executive lounge with beautiful view of the sunrise. Rio hotels are expensive and this is no different. I would stay here again definitely.

Americans, those with more dollars, less time and even less inclination to use their grey cells end up the JW Marriott. Regrettably, I fell into that category.

For starters, if you're there for business, note that the rooms are not WiFi enabled. They do have a cable connection but it isn't of any use if your computer does not have a port for the cable as was the case with my AirMac. Secondly, while the alleged paid upgrade to an "executive" room gives access to the 9th floor executive floor where there is WiFi you will find yourself in a room with dark tinted windows meant to protect against the eastern sun. At night, it has the effect of a disco or worse a room for gangsters.

The staff are generally helpful but barely after checking in I was literally accosted by a rep from H Stern who shoved a package of supposed discounts including a "free" car ride to their factory to check out their gemstones. The lobby bar at the 1st floor is decent but with only 3 tables next to the windows overlooking Copa beach. When I asked the waiter for one of those tables he responded it was "reserved" I sat further inside next to the "reserved" table by the window for over an hour eating and no one showed up. When I pointed that out to the bar manager he apologized claiming that someone had reserved it and did not show up - I'd sooner believe in the tooth fairy.

The fitness center is on the top floor with nothing really to write home about. Again with tinted glasses and 2 treadmills along with sundry other equipment. The pool, recessed in the rear area of the roof, has no views of the beach.

The Lobby of the hotel too has a tired look and needs a major renovation.

Incidentally, I see that management does not respond to TA reviews, at least in the English section.

Great location of the hotel, just across the street from Copacabana Beach. Also easy access to all the touristic or business centers. I had an oceanfront room but agree with others about the rooms overlooking the corridor. The room was spacious and clean, the hotel staff friendly and helpful. Great food (recommend sushi) and caipirinha in the bars. If you need, front desk can organize tours for you and drop off at the airport
One of the bests hotels in Rio, would definitely consider it again if we found ourselves in Rio.

I usually have a great experience at Marriott properties, but this property in Rio was not friendly to us Americans! The rooms were adequate, we did have to be moved after one night because it was so noisy with some water running noises...but the staff was really not helpful or friendly. They were bothered to make change, if they did make it for guest. The wait staff in the restaurant was very slow.... great place to visit, just choose another place to stay!
