Pressure is nothing other than gravity pulling down everything that lies above you. So if you go deep enough, there will be enough gas above you to create enough pressure to make water liquid, or even solid.

I wonder whether it will be possible to build a floating city somewhere in the middle of that massive atmosphere. Air conditioning will probably take up the majority of the city's energy consumption, but hey, if you've got water, you can get oxygen, and if you've got boiling water, you can make electricity. Actually, it might be easier to live on this planet than to live on Venus (450C, all CO2).
