First of all, this is the place to stay in São Paulo! I took my wife for her birthday and we simply had an amazing time.
Amazing room with great views of the bridge and the river (stayed at a Club King room), a more than excellent service, breakfast and spa. You can use their gym and indoor/outdoor swimming pool too.
The bathroom is also very nice with great bathroom amenities by Granado.
It's near two big shopping malls and you can always get a taxi by calling the reception.
They cleaned the room twice a day and always made sure that everything was just excellent.
If you come to São Paulo and have the budget, stay here.
