We knew from the rating that it would be a top class hotel but as a "four star" in Sao Paulo we were expecting something better. We arrived and no one was speaking in English (being Italian I understand 50% of what they saying), and when I asked them why they kept speaking in portugese in a fast way so we didn't understand anything, they started laughing at us very loudly. The personel was very rude and the atmosphere was not agreable at all. The neighborhood is very dodge as well and I don't recommend it at all to anyone. Luckily we stayed only two days and we are leaving now.
Seems like you are a bad encounter than an actual guest.
