Stayed here for a few days before we went onto Monaco for the Grand Prix. Our room faced the side + was quiet. no problem with noise from next door either. Our room and bathroom was small but was fine. Location was fine - 10 minutes to the train station and the same to the main shopping area and resturaunts. Only 5 minutes to the Promonade.
My only complaint was that the jacuzzi is no longer there, Apparently we had to pay for the gym which we thought was free. We didn't use it, after bringing my stuff over!!
But if staying in Nice, we would stay here again.
