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.
