Neuenhof is too small to worry about the getting-around.
Neuenhof is situated near Baden and has little to offer even for the off-the-beaten-track enthusiast. Simple. There's a big street and a couple of old houses of which you find tons elsewhere.
Neuenhof is nothing special. Hikers might pass it as it is situated near the Rüssler Hill, which is on the path for hikers going from Baden to Dietikon and starts at the Wettingen monastery.
Nothing particular - few supermarkets and a gas station that's open till late.
Try the following restaurants (in the order of appearance):
Please, do yourself a favour and visit Baden.
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.
