Ibie Wien Messe seemed like a nice enough hotel and it's definitely worth a stay. Though, we did have a few complaints. First, the food in their restaurant was somewhat overpriced and with overall low quality. Second, they didn't clean the room properly. We brought up some food on our first night (we stayed three nights) and the leftovers was never removed by the room cleaners. Third, you couldn't sit up straight in the bed with your back leaned up against the wall. If you did, the whole bed would move away from the wall. All in all though, we did enjoy the stay.
