I stayed 30 days in a 2 bedroom appartment, while at mougins for professionnal reasons.
the appartment is quite big (considering the dimensions of most french appartments), i had a balcony with table n chairs with a superbe view over the hills...a fully equipped kitchen...fonctional house, no fancy decors but everything was clean and nice.
staff was very nice n helful,service was ok.
well located (in a main road but not noisy;near bus stop,train station,fitness center,supermarket and mcdonalds)...the whole place is safe, and all appartments/villas have parking spots...

i had load of privacy (which is smtg i like).
Breakfast was an option

please note that citea Mougins is a "residence hoteliere", if you are looking for a place with all those hotel amenities (concierge,retaurant,etc) this wont be the right place for you, in Citea Mougins you rent the place, but you have a very independent life: restaurant is only opened for breakfast; but during the day one can cook one's meals, order some fast food or go and eat out. The receptionist might help you with your order...
