Do not understand the 4 diamond/star rating system...

Do not understand the 4 diamond/star rating system. Been at cheaper hotels with better wifi, TV, beds and rooms. Wifi spotty and slow, bed with a soft spot in the middle and firm on the sides, TV did not work one night, room had poor water pressure, and construction started outside at 4am. Otherwise nice historic grounds and service, just none of the things I care about in a relaxing hotel stay.
