Any recommendations for responsible lodging with a family in Cassis?
The hostel there might be a good option. It's basically a really nice house with two dorm rooms and two private rooms. There's a pool which would be great with kids. You can rent out one of the dorm rooms - one has 4 beds, the other 6. http://www.hostelworld.com/hosteldetails.php/Cassis-Hostel/Cassis/49839?sc_sau=sfab&sc_pos=1
Thanks for the suggestion! I will check it out.
