Best hostels in sao paulo?

I am planning on visiting Sao Paolo this year and am willing to stay in luxury hotel so would appreciate now much if someone tells me what are the best hotels in Sao Paulo and I would like also if they are located in the center of Sao Paulo. I am interested in staying at the hotel which has got all the facilities including shopping possibilities. Thanks much!

I think that the Renaissance Sao Paulo Hotel would meet your needs the best for it has restaurant, boutiques and all other facilities including outdoor poor, massage and sauna room, you may go even to a gym there and make your hair done and what is the best the room service is available 24 hours a day. It is stylish and if you ask me it is the best hotel in Sao Paulo and you won’t have any trouble reaching the downtown for it is in the middle of the city.
