The 'Landhaus' restaurant also has a few hotel rooms; never entered it, but if they're anything like the restaurant then expect basic Swiss standard at something like Sfr.100 per room per night.
Else the Kloster Wettingen has rooms. It's just across from the bridge on the other side of the Limmat, so for the pleasant 10 minutes walk from Neuenhof you get a picturesque, pleasant and quiet place to stay over. Plus their restaurant is better.
Anything else, you're better off staying private or go to Baden.
