Unless you are visiting the Cannes Mandelieu Space Centre, Mercure Cannes Mandelieu Hotel is in a very poor location. It sits in the middle of a battered industrial park in the shadow of Cannes airport. Although the bus station is nearby, there is very little public transport and taxis are expensive. It is a convoluted walk to the beach and it is about 7km to glitz of Cannes' beating heart. Moreover, some of the rooms are external to the hotel and can be noisy - you reach them via an external walkway overlooking a courtyard. And the furnishings are fairly basic. Still, the Wi-Fi works, the pool is picturesque, the staff are helpful and the hotel sometimes runs a free shuttle bus into Cannes in the mornings and the early evenings. But none of that can compensate for the dreadful location. 5/10
