The old district of Nice is one of my favorite areas of the city! During the day, the atmosphere is really cool and I loved walking through its little streets and seeing some of the traditional orange / red buildings. I'd recommend you to walk past the beautiful "Cathédrale Sainte-Réparate" and to visit the souvenir stores. And last but not the least, in the old district, there is FENOCCHIO a.k.a the BEST ice cream shop I've ever tried in my life! Their ice creams are just incredible and so tasty. You can try a lot of different flavors. My favorite combo was: lychee & avocado and I used to go to the shop every night to get it!!! OMG, my mouth is watering when I think of that haha :) Assitan <3
