The barge is on the water which was lovely to have breakfast by, but there are mosquitos at night.
My room was upgraded for free which was kind of them, but the AC only worked as a fan, not a cooler, and overlooked the entrance walkway, which was noisy when people arrive at 5am, and many people not respecting normal sleep times by being quiet when returning from a night out.
The common room was large and comfortable and overlooked the water. Bikes available for use, but I didn't partake as I was happy walking everywhere. Close to newly opened Museum of Contemporary Arts. The New Belgrade area has a very relaxed, open feel compared to Belgrade proper and was a great start to my visit in Serbia.
