A small hotel at city center, which is worth the fare.
Nice room, with fridge, right mattress to avoid back pains, clean, with cafeteria and breakfast separate spaces. Simple, but enough to keep you running till the evening is the breakfast. I ask for a quiet room, so I hear nothing but my breath. If your neighbors are a bit careless you hear the noise.. For 16 euros per night , you dont ask for more.
I fully reccomend. In 100 mtrs, you are in the sea side and the cafes and restaurant. Close enough from Tunis only 75 km away. The best is to exit at Hammamet north and follow all the way down.
