I have spent a lot of time in Cannes over the years & stayed in many Hotels, all 4 star up.
Eden's location is great, almost all the way up on the busy shopping street Rue De Antibes.
Rooms are small, not very clean & all in all I was not very impressed since it claims to be 4 star.
I tried the spa that is located in the bottom, next to the garage I think. Not very cosy. The massge was good but too expensive for what it was. I also tried the pool, way too much clorine, felt sick!
Breakfast was ok. Never tried room service. I won't come back & I won't recommend this hotel.
