Head to the Bardo Museum in the morning, returning to the medina for lunch to explore its souqs, tiled dars (mansions) and zaouias (saint mausoleums). Wind down over dinner at Dar El Jeld, housed in one of the medina's most handsome dars.
The next day, explore the ancient sites of Carthage and then enjoy a late-afternoon wander through the picturesque village of Sidi Bou Saïd, admiring its blue-and-white buildings, visiting its contemporary art galleries and enjoying a coffee at Café des Nattes, before heading back to central Tunis for a seafood dinner at Chez Slah.
On day three, wander through Centre Ville, admiring the magnificent though dilapidated 20th-century architecture, visiting the Marché Centrale and taking a lunch break at chic Le Carnot in the Institut Française. In the evening, attend a performance at the Théâtre National Tunisien Le 4ème Art.
On day four, head back to the medina for some shopping in the morning and then decamp to the upmarket seaside suburb of La Marsa to promenade on the beach, enjoy a coffee or tea at Café Le Saf Saf and browse its designer boutiques.
