Is therr any good hotel with kitchenette or kitchen in central Switzerland?

I would prefer to cook meal at the end of the day and stay in central location Switzerland where i can just do day trips to places with good train connection. I am planning to to spend 7 days.

What you want is not a hotel but a rental appartment, a pension or a private room in a hostel. Check out the Backpacker's Villa or Balmer's Herberge in Interlaken.

Another option would be the Rugenpark B&B, also in Interlaken.

Hotels do not have kitchens their guests can use.

Do a google-search for:

hotel "zimmer mit k眉che"

We've stayed in a number of Reka apartments and most if not all have kitchens.

i would say living ther once my self Swizerlnad has one of the best kichtens in the world. If your staying in a hotel or wlking down the streets i'd defenanly say, there's always food (that's good food) and just to make you aware ther acually isn't as much fast fod as over here in America since they do like cooking themselves!! But be prepared, good food can get pricey!!!!!! hope it helped
