Oops, I'm sorry I refered to your girl as a boy. I hate when people do that to my girls, especially since they are almost always decked out in pink or dresses.
The kitchen would be another good area. Any area that you can block off easily enough and has floors that would be able to withstand accidents and the subsequent clean up.
As far as the pee pads go, I think the best thing to do would be to take the pad outside in an area where she normally goes and then praise profusesly when she uses it. The idea is that a potty on the pad is a very good thing. Hopefully, you will gradually be able to move the pad indoors. It will be more difficult since you are in a townhouse though and won't have the luxury of kind of inching it to the door to the house. I've always lived in highrises, so I started with pad training. I read an article recently about going from outside training to pad training; let me see if I can find it.
