Dear participant, we kindly invite you to make your own arrangements for accommodation for your stay in Nice. The city is full of possibilities and reasonably-priced hotels (3* 60-120€; 4* 90-140€). You have to make your own room reservation directly by phone, via Booking or TripAdvisor websites or by logging on to the hotel website.
As an example, close to the Sea (less than 50m) and close to the Palais.
