Our room (Queen Anne) should have been wonderful as it overlooks the gardens and lake and is very comfortable. However, it had been shown that afternoon to a couple planning their wedding and had not been cleaned: there were unspecified liquid spills on two surfaces and the floor needed vacuuming. The rose petals on the bed were fine, though rather unexpected ...! The toiletries are disappointing for a hotel that could go for a more luxury experience.
We ate at the restaurant, both dinner and breakfast. The music was too loud and way too much unrestful jazz: inappropriate to the setting. Service was mixed: the young chap who checked us in was great, but the evening staff seemed tired and bored and not really wanting to be there. Breakfast staff were very friendly.
Overall, it is a great location, especially for the airport; these are easy fixes so I would hope would be addressed.
