April vacation in New Hampshire?!?

My boyfriend and I are looking to take our April vacation in New Hampshire. We are two young adults who enjoy the high end feel of our city hotels, but want a scenic location that is perfect for walking around, taking photos, and just a great place to relax. So far we've been recommended to stay in the White Mountains and North Conway. Our budget is $100 a night. Can you recommend somewhere for us to stay that you think a young couple looking to relax would enjoy?
