I am living in Eindhoven and I work at Best. Everyday I drive about 17km(15 minutes without traffic jam). I just work beside Makro. You can take bus 141 from Eindhoven station to Best Makro. The trip will take you about 25-30 mins. I can also give you a lift if times fit well. For your situation, I suggest you'd better rent a room in Eindhoven. Best is very close to Eindhoven but Eindhoven is a bigger city. It will be more convenient for your living conditions.
