"The room wasnt bad for the price. My only complaint is with Hotels.com. the description of the rom was a bit misleading. We ended with two twin beds that were not next to each other. Me and my wife slept across the room from one another."
You can spend time browsing the exhibits at Kommern Open-Air Museum in Mechernich. Stroll along the lakeside or visit the spas while you're in the area.
