Take the train
Why not walk the 100m to the station and hop on the train to Ile Rousse? The trainline hugs to the coast so on the way there, check out the beaches you fancy a stop at on the return journey.
Eat on the Place de l'Eglise
Just a few steps from your front door is the charming, Place de l'Eglise, in front of the pink church of Santa Maria, there are restaurants either side that spill out over the square including the Santa Maria and the Chez Doumé, they offer a good choice of food and cater very well for kids.
The harbourside at your feet
Step just outside for the restaurants of Calvi. Just below you on the quai Landry there are numerous oppertunities for watching the gin palaces arrive in port whilst you sip on a cocktail yourself.
