I'd rate the Sofitel as Nr.1 in Djerba, even above the Radisson, although there are a number of issues. The problem is: Djerba's unsophisticated low- and middle-class crowd and the Sofitel "luxury" brand simply don't mix well. Service standards are appallingly low. You can feel that the staff has heard complaints all too often. If you strike a relationship they are friendly, as typical for Tunisia, but otherwise you are just an anonymous number in a mass operation. The guests at Sofitel are majority French, which positively reflects on style and dress code. Apparently the Sofitel even receives some prominent French guests. Nevertheless, you will see a lot of sandals-shorts-backpack kind of crowd, but less than in the other hotels, such as the Radisson, which is more modern in design, but somewhat "cold" and frequented by an Eastern European clientele. Personally, I cannot imagine a real holiday in Djerba (only stayed one night), but then I am definitely not the target group. Towel cards, breakfast cards, that's not my style. What I found "cheap" is that no personal welcome, not even water was provided for free in the room, although I am Platinum A-Club member. I was charged for the one water bottle taken from the mini bar. But at prices below € 100 per night, what can you expect...
