Booked a one night stay at The Mansion and a table for dinner to celebrate my wife's birthday. Grounds and building (from outside) are lovely. The room booking was for a King room. It was a very large room, small bathroom, spacious kitchen and TV area. Wasn't a king-size bed, but two twins pushed together. The room was clean and tidy, but the state of the decor was very poor, broken plaster, unfinished plaster around sockets, water damage stains on the bathroom ceiling, and loose tap in the kitchen. It's really shoddy for what, on the face of it, appears to be a class establishment. On the plus side, the restaurant experience was of the quality we'd expected as long-time customers of the sister establishment, Becketts in Southsea. Service was friendly and efficient, and the food and wine were excellent. We enjoyed bread and olives (although the quality of the latter weren't great), starters of bang bang chicken and pork belly bites, and both had the chicken supreme for main, enjoyed with a bottle of pinot noir. Breakfast was also excellent, also with friendly service. We would certainly eat here again, but we wouldn't recommend the hotel until they make significant improvements.
