I have a flight with Air China from PARIS to TAIPEI (Taiwan) with a long stop (more than 20n hours) at the Beijing Capital Airport
I'd like to use the "round-the-clock" hourly rented rooms facility that is said to be in the T3-C 2nd floor.

My question is simple: is this facility situated inside the Intenational Transit Area (no need of a chinese visa), and if not, is there a way to get it without a visa ??

Thanks
