We stayed at the Amazon Plaza the night before leaving for a Pantanal trip, so was a good place to stay for that. The room was very spacious, and staff very helpful.
The swimming pool area was being refurbished at the time we were staying, so we couldn't use it, but the lady on reception said that we could use the pool in another hotel (we didn't take up the offer). Breakfast selection was good, and the room very beautifully decorated.
