I was fortunate to stay at both Le Cep in Baune and Chateau de Gilly in Vougeot about 6 years ago on a Butterfield and Robinson bike tour of Burgundy. Both are lovely however, Chateau de Gilly is set off by itself in wonderful settings and is a remarkable chateau. You must have dinner in the cave like wine vaults. This hotel I would go back to again.
Le Cep is nice and is smack right in the heart of Beaune. Nice but nothing special ( as Chateau Gilly is). Biking through Burgundy is also something special. What a way to see the countryside and meet the locals. Would make this bike trip again in a heartbeat.
