Full marks to the Thanington - the rooms were very comfortable (ours had a bathroom bigger than most other hotel rooms we've stayed in!), the staff extremely helpful (their restaurant guide to the city proved very useful), the location good (a 15 minute walk into town), and the breakfast good. Off-street parking is available (although a bit tight) - but not all central hotels offer this. The only small criticism is the lack of a decent cup of decaf coffee, but alas that is true of 90% of UK hotels! Fully recommended.
