Welcome to the Q&A Forum

of course, it depends how much other content you have and are creating. There is also the question of WHAT are you trying to rank on. The keyword stuffing penalty generally hits when the keyword stuffing is excessive and uncalled for. You will probably not rank for "dining room" in the top 10 if the rest of your content is automatically generated. As a very general rule: do not use the keyword on a page more that 25 times and do not exceed 10% keyword density. BUT it may vary from case to case, from keyword to keyword, from market to market.
