Working freelance I think this applies far less to me, however, having been a permanent employee and working with permanent employees, some of whom I am lucky enough to still call friends, I cannot encourage people to strongly consider this advice.

By the very nature of freelancing, I move from company to company and find that how good a place is to work at for anyone is based on the culture most of all and not the facilities, size of company, sector nor location. Remember that you are putting yourself up to possibly spending the rest of your working life there (dating analogy still applying?).
