Is this property really worth 300 euros per night???

My friend is so adamant of going to monte carlo end of april and i was checking the only starwood property here...But im quite shocked on the price tag considering it's only rated as 4 stars (but spg cat 6).

He wouldnt want to stay in LM Nice though it's only a few kms away and insists that monte carlo night life and the clubs/bars are so much better and exciting in MC...

But im still shocked (for days now) with the price tag...i mean it's not hotel imperial wien nor W Opera...

So should i just bite the bullet as 300 euros/night is the going rate at this property anyways or should i find a cheaper property that's not starwood related?

After checking tripadvisor photos and reading reviews at several sites....I still cant believe theyre charging 300 euros/night on low season...

Any helpful advices on what to do would greatly be appreciated
