Beautiful facility. Excellent design with practicality and modern sensibility. The breakfast was outstanding and great value. Service very attentive, professional yet friendly and authentic. Fitness center was on par with any five star hotel. Rooms were beautifully appointed and far bigger than any hotel whether four or five stars.

The room was very nice-lots of room, accessible shower for my mom.However-in the evenings and early morning we were kept awake/awoken by what sounded like someone stomping back and forth.I called down to the desk the second night and was told by an apologetic attendant that the air-conditioning was broken and being fixed.This noise continued until approx 1:30 am and began again too early in the a.m.we spoke with the girl at the desk in the morning who said it was only until 10:00-it was much longer than that-it was the same issue for the remainder of the stay. Overnight on Friday it began approx 1:15am and lasted through to approx 3am-I do not believe this was maintenance but rather a noisy, heavy footed guest. I would have appreciated a room change.(btw-my mom and I both wear hearing aids and I sleep with 'white noise' so this was unreasonably loud) Regardless of how nice the room was - this experience and loss of sleep made it an average experience at best-with consideration for the friendly staff and nice room.

Had a great eta. The hotel is clean and well-decorated in a modern style. We were welcomed with complementary cocktails (thanks to our Marriott status I believe). Room was quiet for the most part. I love that they serve free coffee in the mornings Best of all the hotel is so close to the shops and restaurants in Portsmouth.
