The lounge internet is just a PC like the Hyatt CDG lounge. I have stayed at this hotel dozens of times in the past, but always at a rate under €200. The current prices are ridiculous, but I guess they are getting paid by someone. My most recent stay a month or so ago I used points. Nowadays I choose the Hyatt CDG usually for about €100 or so. The rooms are the same as is the lounge. The only difference is the shuttle. But if you are using T1 you need a shuttle for the Sheraton too. Also the Hyatt has a far better gym.
