I have stayed at the Pullman Sao Paulo Guarulhos many times and this was prob the worst stay. We were located on level 1 which really noisy and the noise coming from the lobby was horrible.
They seem to collect the same details everytime, including when stayed there 3 weeks apart, needing to give email, phone etc details again.
On this last occassion, we booked 3 rooms one of the rooms was for 2 adults and 1 child - however there was only two king single beds in the room when the room was booked for 3. the other dissappointing thing was the room window had a massive crack in it which didn't look safe at all.
First time I was extremely dissappointed staying there.
