If you look at the website, you can clearly see the room size (50 sq m of space) and bed type (two twin beds, not double beds). The room size is large compared to some other Park Hyatt properties. What is now called a Park Suite King in Paris is 40-50 sq m. The Park Executive Suite in Paris is 50-60 sq m.

I don’t imagine four adults sharing two twin beds would be that comfortable.
