We stayed at the Tropical Manaus Hotel last week. The best way to describe it is that its the Shining set in the tropics. A massive complex with a very nice swimming pool in the business center. This place has a very strange vibe. According to the guide books, there is a disco in the hotel, however none of the staff have ever heard anything about it. The restaurants are overpriced for the quality of the food. We were told that the buffet was 25 reals/person. When the bill came back, it ended up being 50 reals/person. The staff wouldn't even let us keep a copy of the receipt.

Overall, an OK place to stay the night, however, I'd advise that you go to a place like the Amazon EcoPark if you want to see the jungle.

We found this hotel rather tired and dated, with a somewhat Soviet or institutional feel to the place!
Eating in the main breakfast room felt like being in a company canteen.
Our room was very dark and we couldn't figure out how to change the aircon settings. Also, walls were thin and we were disturbed by neighbouring room.
It was a 10 minute walk to reception - this is a HUGE hotel!
We ordered something on room service and wrong food arrived - this was, however, remedied once I called them again!

Our room was clean though and I suspect this may have been the best of the bunch in Manaus. Compared to the other places we stayed in during our trip to Brazil, the rooms were not great.

This hotel has an excellent service, the pools are really good, with waves. Private zoo

The breakfast was amazing, with region tipical foods.
Good service.
Far away from the city center, but the only reason to go there is the Theatre. Has a peer where you can take boats for the Black river and jungle rides and unique attractions.
We had wonderfull time at the hotel.

This hotel, built in 1976, seems at least 20 years older than that. The atrium and main pool area have been renovated but the hallways, rooms, and bathrooms appear to be original. The hotel is located on a 100+ acre site in the best part of Manaus, on the banks of the Rio Negro. It is about 10km (6 mi) from the airport and about twice that far from central Manaus.
The Tropical Business Hotel is a newer 20+ story hotel on the same site. From the outside, it appears to be much nicer than the older hotel.
Both hotels share the grounds which, in addition to three pools all together, have a gymnasium, tennis courts, and a forested area. There is also a small zoo with a sole jaguar, several species of monkeys, a cayman, and several species of birds, all in small caged areas.
The original hotel has a nice dining room, a complimentary full breakfast in the coffee shop, and a small grill, as well as a bar in the lobby. There is a small cluster of nice stores in a open-air courtyard off the lobby. The hallways are long and large and the rooms are larger than average. The halls and rooms show wear consistent with their age but are clean and well kept. The grounds are also well maintained.
There were two ATMs in the lobby but neither worked with my ATM card from the U.S., so unless you plan on changing money at the desk, get cash at the airport ATMs before you leave for the hotel.
