I always stay at the Corner House Hotel,
http://www.thecornerhouse.co.uk/ . It's a small, family-run hotel. The big hotels annoy me -- they're impersonal, and expensive, and then the bus from the airport only comes every 45 minutes and they have the cheek to charge you for it. The last straw was when at one hotel we set an alarm call and their clock was wrong so it called us two hours early, and we told them in the morning and they didn't seem to care.
In fairness, the economics may depend on whether you need to park a car. A smaller hotel would normally charge for parking, and the big hotels may not, so that would give the smaller hotels less of a price advantage.
