From the amount of praise they receive on this forum I always thought Aman were the gold standard of luxury hotels with service to match. The fact that nobody seems to have even had the basic courtesy to reply to a complaint is staggering. I think you would get that from a Hampton Inn let alone a €1000+ per night luxury property!
I must admit it makes me think that if that’s the standard of their service when things go wrong - you can keep ‘em.
