hotel Sidi Driss: matmata
It's one of the larger underground houses (troglodyte homes) turned into a hotel, There are 145 for 20 rooms and a restaurant and bar. I can't comment on the rooms though, since I just wanted to visit the location.
It's planet Tatooine here. Hotel Sidi Driss is where the interiors of Uncle Owen and Aunt Beru's house were filmed in Star Wars. Strictly for die-hard fans or tour groups.
