Jianmen is a town, not a county. Jianmen Town belongs to Jiange County. After you go, you can choose to stay in a hotel on Jianmenguan Street or go to the county seat. The security of Jianmenguan is still very good, so don't worry about security. As for the price, it depends on how you position yourself.
If you have any questions, I will continue to answer them for you, because as a swordsman, I very much welcome you to visit Jianmenguan.
