We stayed in the Mercure Hotel for three nights while traveling through Germany. Having read the other travellers reviews we were a little bit worried about the railway track noise coming from the nearby railway station that other guests have mentioned. I can only say that the noise didn't bother us to much as the hotel was rather empty while we were there, and we sort of accepted it, having preferred this kind of noise over a noisy guests! Should we stayed in the hotel during a colder weather with the windows shut it wouldn't be an issue at all. The most important was that the hotel was really clean, modern, very comfortable, and centrally located. What's more, there was a good quality Bosch tea/coffee machine provided in the room together with a large bottle of a quality local mineral water supplied every day, which was a nice touch. There is also an underground parking space for the car should anyone need it. If I ever return to Bad Oeynhausen I am certainly going to stay in Mercure hotel again. P.S. Have I mentioned the best quality crisp bed sheets?
