Hotels and alternatives
Finding a room of your liking represents no problem in Nefta. The town has both budget, middle and high class. Value for money is good all over. You do, however, pay quite a bit extra if you go for a room with a view over the Corbeille. In my view, it is only the Sahara Palace which has rooms worth extra money. But that is also by far the most expensive place in town, and reputedly the worst service. Bel Horizon, nearby, is a good alternative, far cheaper, still very nice and with friendly staff.
Restaurants and alternatives
Good selection of restaurants, both independent and in hotels. All classes and price levels.
Not too much. If you want to do something more sophisticated than drinking your beer in an empty bar, you will have to go to one of the hotels overlooking the Corbeille.
No problems. Banks, ATMs and exchange service in the receptions in the better hotels. Many shopkeepers will accept to be paid by VISA or MasterCard, provided that you buy above 10-15 dinars.
Direct bus connections with Tunis, for other destinations, travellers should go to Tozeur by bus or taxi (25 minutes).
