We easily fitted our family of 4 (with two large lads) into a room for 4. The kids loved it because they were on the mezzanine deck above our bed. The little lake down the hill was great for swimming and the village is worth exploring in the evening.
We used this to break our journey from England to Switzerland because it is on a good route from Calais down to German/Swiss border region and a very reasonable price. Strongly recommended.
