Standard business hotel centrally located in SP with a nice lounge. Lounge attendants are friendly and helpful.
The only thing that I do not like is that booking on Marriott's website is in US$. The front desk converts the rate into Reais and bills the stay in Brazilian Reais and the conversion rate is not a standard rate used by Visa/MC/Amex, but an arbitrary rate advantageous to the hotel, essentially adding 5-10% to the room rate booked.
