I prefer a love motel than taking a garota to my place. Love motels allow 2 or more garotas to be with you, you don't have to explain nothing.
Another very good place is Motel Overnight, located in Barra Funda, 15 minutes drive from Paulista or Centro.
The diferential of this hotel is they have private pools in their upper class suites.
