DH and I have our 15th anniversary this year and we're planning a couple of child-free nights away. We need to be within 2-3 hours of London. We'd like something in a lovely small town or in the countryside, probably something small / personal rather than a big all-frills hotel, but nice and luxurious. Not fussed about things like spa facilities but would like to be able to have a good dinner in the evening.
Any ideas? Budget about £150 or so a night, maximum.
