I can highly recommend the Andover Guest House. It's located in the centre of what is a very small town. The P.O. is a short walk down the road, a Diner is right next door and across the road are 2 well stocked convenience stores.
On the upper level they have a low cost hiker bunk room which has its own 2 showers and a toilet, or if you wish they have reasonably priced private rooms. The place is very clean and beautifully furnished.
In the downstairs lounge they have a large TV (cable) and about 100 videos to choose from plus free internet access.
It was the best hiker hostel I stayed at during my thru-hike. The other hostel in the area is quite away out of town.
