Our family of four stayed here on our roadtrip throughout France and Germany. I either didn't read carefully, or they were out of family rooms with ensuite bathrooms, but we ended up with a room without a bathroom. It wasn't a huge deal (and it's always a great lesson for kids not to take bathrooms for granted), but it was still a little inconvenient. Also, the hotel did not have air conditioning and it was quite a hot day - the windows open helped, but the traffic headed into Oppenau was quite loud, even at night. Breakfast was quite big and good, and the hosts were very kind and spoke a variety of languages. The guesthouse itself is quite cute with gardens and playgrounds out back, and well-decorated throughout.
