Minimum 5 star.
This hotel is beautiful. I have nothing bad to say about this hotel, our whole experience from the bell boy picking up our suitacases to checking out was seemless. We enjoyed our whole stay and would recommend this hotel to anyone visiting the area.
Outdoor swimming area is better then the pictures, the rooms are good size.
The entertainment at the hotel is great, a piano bar and games room.

Mabu - huge! Great pools and probably great for kids but do not expect peace and quiet! Rooms are dated and there is maintenance work going on. Service is poor and rooms are not cleaned to a very high standard. If you pay rack rate for this then you must be totally crazy! We found this to be a bit of a comedy hotel.........the staff must be having a real chuckle at the guests paying the kind of money they do! Very loud aqua aerobics every day too...

Recently stayed in foz De Iguacu over xmas it was fantastic the service the rooms and the food are great ,i recomend to anyone going to Foz.
The waterfall is one site worth visiting and better seen on the Brazil side as you can see more because there are more falls in Argentina.

Excellent location, 5 mins from Foz de Iguacu, 15 minutes from the airport and 20 minutes from the falls. Very clean and well maintained - the rooms were sparkling clean, as were the pools and all the public areas.

The pools were a bit on the small side (coudn't actually swim much), but this was made up for by the lovely temperature which allowed swimming day and night. The pools are fed by a thermal spring, and offer different temperatures of pool as the water flows down from one to the other. The constant replacement of the water (every 4 hours) means there is barely any chlorine and it is lovely for lounging around in.

Big buffet breakfast included in the price, with amazing fresh fruit. Food and alcohol was reasonably priced generally, though the buffet dinner could get a bit same-y if you were there a few days.

Very helpful staff - not many spoke English, but as the previous review mentioned, they would always go and find someone who did.

If you can stand the price, definitely recommended!
