I just found this video room review of The Cosmopolitan of Las Vegas on YouTube. The video does a pretty good job of showing off one of the wraparound suites at the hotel.
When The Cosmopolitan was originally conceived, a great portion of the units were intended to be sold a condos. From this video it's clear that much of that condo influence remained in the design of the suites.
It's pretty rare in a Vegas hotel room to get a full sized fridge, kitchen and washer and dryer (not pictured in this video, but included in most of the suites). These added amenities will no doubt come in handy to Cosmo guests.
