This hotel is great for vacations with children.
Every detail to make your trip enjoyable with kids has been taken care. From newborn babies to ages 14, everything is covered, and I mean EVERYTHING.
Some examples:
There are feeding rooms near the rooms fitted with Microwave, Fridge, Milk, cookies, bottle sterilizer, etc in order to feed your babies at times when the restaurant is closed.
Then there is a babies + toddlers house, which is equipped with everything from Cribs to special baths, etc.
Then there is a kids club with a team that takes care of the children and they make separate activities depending on age.

As for the rooms, they are OK: good size, well appointed, a bit outdated and bad maintained. (typical in Brazil)

The food is alright, I even would consider it slightly above the standard of mass market/ all inclusive food.

The infrastructure in general is good, nice swimming pool, beautiful beach, wonderful sights, etc

We spent a great family vacation with your 2 year old daughter (she spent a wonderful time).

The really, really bad thing about the hotel is that it takes 3 and half hours to get there from Rio de Janeiro Airport on an horrible road which will sure make you sick. I would not return to this hotel just because of the road traveling needed to get there. I know it is not the hotels fault, but it can certainly affect your vacations.
Honestly I did not look too much, but I assume that there good hotels on the beach in Brazil with such a good infrastructure closer to an airport and without this painful road trip (very bad with children also)
