Question Affordable and Clean Accommodations in Lauterbrunnen?

I'm traveling to Lauterbrunnen in early September with a group of three and looking for recommendations on where to stay. We're hoping to find something that's clean, comfortable, and moderate in price. Does anyone have any suggestions? Also, if you've stayed in Grindelwald and think it's a better option, I'd love to hear why. Thanks in advance for your help!
