I stayed at the Mercury Inn in June. The rooms were nice and had a very quaint New England feel - the exact thing I'm looking for in a B&B. The breakfast spread was delicious and I looked forward to the yogurt dish every morning. Plus the baked strawberry cobbler was amazing!
I stayed in a larger room with a king size bed, window bed/seat and private bathroom. The room was quiet and I loved that it had well working WIFI and AC. The bed was comfortable and was topped with lots of cozy blankets.
The inn is also close to local restaurants so it was very easy to walk to and from dinner. I also liked they had parking on premises so I didn't have to worry about street parking.
I would highly recommend staying at the Mercury Inn if you are looking for an affordable and quaint B&B experience.
