I often travel to Augusta, Maine for business and when I recently discovered Maple Hill Farm Inn, I was pleasantly surprised. Uncommon for B&B's but important for business travelers, the inn has TV's in every room and complimentary wi-fi throughout. Rates are very competitive with local hotels.
The only downsides from a business perspective and the reason for not giving a 5 star rating is that it is a little off the beaten path and that because of the B&B atmosphere, it has a somewhat slower pace than the chain hotels. Excellent value and super clean!
