Comparing with the Ibis Hotels from São Paulo City the Manaus one was really good. The breakfast has many different options and for the other meals the menu has a good variety of food and for a acessible price.
We also liked the fact of the parking lot beeing free of charge.

Bah, cheap hotel, little reastaurant which doesn't pretent to be called restaurant...
Clean as any Ibis uses to be.
Staff is smiling and showing courtesy as the Brasilian culture want to.

I stayed at Ibis Hotel well over a year ago, during my south american trip. I had (and still have) a specific cultural interest in Manaus, hence I spent there a whole week, something people usually don't (Manaus is pretty much considered a mere start/arriving point for Amazonas adventures). And I were even keen on paying that bit extra and stay in a nice hotel, the Ibis, that is.

Well, to make a long story short, the hotel is nice only on paper (or on the web). Their rooms are definetely not what you would expect from such a famous brand, although I did not experience any extraordinary problem with humidity, such as in the two previous comments. The restaurant is truly bad, I must give in on that.

Anyway, 24 hours in the hotel were long enough to realize that for those 60 euros I would have definetely been better off elsewhere in town. And spent the rest of the week at excellent Mango guesthouse (30 euros cheaper, moreover...)
