If you judge the hotel purely as a hotel, of course you will be able to find better hotels. But this is an establishment that was built in the middle of nowhere but jungle and they have power and water (including hot water) 24/7 and even wifi in the lobby area. I have done the safari tour and also stayed in jungle in a different country before and let me tell you, it is true luxury.
3 square meals are served everyday (start and end time are strict) so you will not go hungry - only the issue might be after a few days of staying there, meals become predictable but as I said earlier, you are in a middle of jungle and you really learn to appreciate the variety and quantity that they offer. Accommodation is all bungalow style. This is one of a very few places that are right by water that doesn't go under water (literally speaking) during the flood season so you can stay here at any given time in the year without worrying about it. Very convenient location to do all sorts of Brazilian Amazon excursions from. This includes going to 2 water meeting points, monkey feeding, night boat cruise, indigenous cultural places, anaconda zoo (?), piranha fishing...to name a few. And from what I understand, because the acid level of water is very high, this is one area along Amazon where malaria is not an issue. I am not a doctor of any kind, but I can definitely attest to it that there were hardly any mosquitoes.
If you have never done a trip away from what we consider "civilization", this area will provide you a nice mix of convenience that our modern life provides while still being able to enjoy some wild life. I have done trips where you need to use candles after a certain hour or wild animals are walking around your tents while you are sleeping or all you have to get washed up is cold water no matter what the temperature is. You will not run into any kind of these things at this location yet be far enough away from everyday life.
