Hotel was great. Clean and the room was comfortable. Front desk staff was very friendly. Breakfast in the restaurant downstairs could have been skipped, not really worth the price.

Nice hotel and close to everything in downtown Portsmouth. However I thought the $40 for parking was a little steep and a microwave in the room would have been nice.
