Is 600£ for a night at Mandarin Oriental Hotel good value of money?

I don't think that 600£ is a good value of money for a hotel. Usually you book hotel when you are on holidays or business trip. In case of business trip you don't really want an expensive accommodation. On the other hand when you are on your vacations, you enjoy sightseeing the city that you are staying in. In both cases you can't or don't want to sit inside room. Paying so much money for spending only nights somewhere seems  as such a waste. Everyone decides how they want to spend their money, however hotel room this expensive doesn't seem like the best investment.
