Terminal 4 is badly connected to other parts of the airport. The free shuttle to T123 is only 4 times an hour. From T5 you're better off taking a service bus (which is free).
From T4, it's quite a long walk over to the hotel itself. Admittedly it's in a covered walkway but if you have lots of luggage it's no fun.

I'd say if one of your flights doesn't use T4 then give this some careful thought.
