The most impressive hospital I've seen in terms of aesthetics is Atlantic Regional Medical Center in South Jersey. I did my residency there. It's part of the UMDNJ-Camden program.
The hospital, at least while I was there, experienced high profitability and benefitted from a large upswing in the population of the local area. As a result the hospital was able to invest several million dollars into itself, and provide facilities that could provide individual patients with a room on the order of a high class hotel room with internet.
The hospital put in plenty of good artwork and other calming things such as waterfalls and large fishtanks with tropical fish in waiting areas.
The hospital added plenty of other pseudo-google like employee benefits such as free to cheap membership at the hospital's life center which was pretty much the best gym in south Jersey, a health account that allowed you to plug in your fitness center data into an account you could acess at the hospital.
The next best hospital that comes to mind was a hospital in north Jersey, forgot the name--(nuts).
