This is by far, hands down, the best hotel you're going to find near Portsmouth, NH. Even in the dead of winter, it was everything we could ask for and then some. When you stay here, you're not really close to town, per se, but you don't need to be! The restaurant, Salt, is fantastic, and when the breakfast buffet is running (it will be if the hotel has a certain occupancy rate), it's an excellent value. Otherwise regular breakfast was also a real treat.
If you're looking for a gym, this one is above normal hotel standards, and the spa is excellent. I can't wait to go back when it is warmer and take full advantage of the amazing facilities!
