It is incredible how Hilton hotels are so different in Latam and particularly in Brazil. If you compare this hotel to Hilton Sao Paulo, the hotel in Rio is bad. And I'm not saying the Sao Paulo hotel is great, but just to illustrate.
This Hilton Rio is neither a resort hotel neither a hotel for business travelers, which I believe it creates all the issues. It is really difficult to tackle both audiences. If you are planning to work I do not suggest the hotel, lack of amenities and services. The hotel is old, rooms are outdated and need to do significant investments to keep the pace for a 5 starts hotel
