Here are some pics of Charlotte @ her apartment in Monte Carlo: Charlotte Casiraghi Back in Monte Carlo | RDuJour
Is her apartment inside the beach club property? Cuz she is seen leaving and there's a sign that says "beach club". The apartments seem nice. And it's a big complex with all the units close knit, row upon row of balconies overlooking the garden.
This pictures are taken from the beach bungalows in the beach club. The beach club is right next to the Monte Calro Beach Hotel and there are a certain number of day-time bungalows rented. But they are not appartments or hotel rooms. They offer dressing facilities, a little kitchen, storage space and the bigger ones have a little living room for receiptions and their private terrace.
