This is a nice property with an accommodating staff. However, a few little things keep me from giving it the highest rating.
The property is on the water -- currently a bit hard to find with GPS because of local bridges being out. Not the hotel's issue but do beware if you're relying on a nav system to get you there. Call ahead and have them send you directions.
Check-in was very quick. There are only two elevators for a very large property but, surprisingly, never a wait. Rooms can be a LONG walk from the elevators so, if mobility is an issue, be sure to ask for something fairly close. Views from the rooms vary but most have some sort of water view.
The basic king rooms are reasonably spacious and modernized. There is a desk and small couch. Desk chairs vary in comfort (in two stays, one chair was great and the other terrible). Bed is comfortable. Bathroom is modernized with ample space. There is an in-room mini-bar, a safe, and bathrobes. There isn't an overabundance of soundproofing so, if your neighbor takes a shower at 4 am, you'll know it. Overall, rooms are fine but I didn't find them special in any way -- nothing wrong but also not memorable.
The restaurant is both good and bad at the same time. The food is quite good -- many choices and each of them was tasty (pasta with shrimp and lobster is a standout). This is true for breakfast and dinner. The downside is the service and atmosphere. When the restaurant is even moderately crowded, service is beyond slow. We spent more than 90 minutes on a two-course dinner, and breakfast routinely took 30 minutes unless you limited yourself to the buffet (which, BTW, is good). The acoustics in the restaurant are terrible -- something about the design of the ceiling means everyone can hear conversations from other tables at a very loud decibel level. It's almost impossible to have a quiet, or private, conversation -- or not to hear those around you.
The concierge lounge was essentially closed (due to the off season). There was a cooler with cold soft drinks/water but the room smelled horribly stale (think of a room that hasn't been aired out for six months). Not inviting. Things are probably better in the high season.
The hotel is not walking distance from anything. Downtown Portsmouth is about a 10-minute drive. Not a problem provided you have transportation and, as noted, the hotel provide most amenities you could want.
The hotel staff is anxious to make your stay pleasant and, overall, this hotel pleases. However, the differences between good and excellent are found in the minor details and a few of these are lacking.
