On the (very) short list of Hammamet's most stylish hotels, Russelior is one of the few in town that's actually worth its five stars. Service is impeccable, and its beautiful 3000-sq-metre spa and huge indoor and outdoor pools make up for the fact that its location requires a five-minute walk to get to the beach.
Note that it's a dry hotel, so no alcohol is served at its bars or restaurants.
