Lucky us - we found time ( and money ;-))  to go on a short trip to beloved france. Most of the places we called were fully booked but then kevin found Château de Germigney in Port-Lesney. It's only a 2 hours drive from bern and in the middle of the beautiful french jura.
The Hotel is surrounded by a lovely park and has a natural swimming pool. The decor is not really my type, to much mixing of styles but I did not care to much. People are friendly and the breakfast was delicious.
We paid 130 Euro for the room 15 extra for the breakfast.

They seem to have a very good Hotel (high class) Restaurant but we ate at their Bistrot in town - a very good choice.
