If she is doing "in calls" in other words staying in a room and seeing clients then she is paying for the room.  If, OTOH, you have made a special arrangement to see her and you will be her only client she will probably book the room but pass the expense on to you.

Incall means you pay the provider one fee for everything.

I always have and then got smart and rented a furnished condo. I was paying more for hotels than the condo. Now I can feel justified in my rate and I have a fabulous place to entertain.

SHYAH! If you have the credit to rent a furnished apt. ...!

I am staying in a semi-nice hotel that is actually provider friendly, but I am paying through the nose! One week in a room would be almost equal to a month's rent in an apt.!
..around $3,000.00 plus a month!

It's time for you to start doing some networking. I realize that most apartment complexes etc. does a credit check and they want to verify employment/income. Ask around, I know that CL isn't the place for advertising our services, however you might find a place there (look for something to rent from an individual not a complex) and talk to your clients..maybe they have something or know somebody who does.
