Absolutely phenomenal, we’ve only stayed at one other Waldorf Astoria, the Rome Cavaliery. The Amsterdam Waldorf Astoria is 1000 times nicer. We were upgraded two levels being diamond members. The room was very nice. What makes this hotel stand out are the employees. Every person treats you as if you were royally. Zero snobbish attitude as some fine hotels have. The concierge was wonderful and was able to book us 2 massage appointments with our right schedule, diamonds receive an additional 30 minutes! We mentioned we were here for a Scorpions concert and when we returned, an ice bucket of beer and a lovely card with a picture of Scorpions! Every door was opened for us, all sincere and genuine. Ah the breakfast, diamonds are able to order 2 separate items plus whatever nonalcoholic drinks. We had lovely eggs Benedict with smoked salmon, Belgian waffles, French toast all the americano’s we could drink along with fresh squeezed juices. The only bad is that our stay was the first 5 days of 18. Now no other room, service or breakfast looks good!! Sincerely thank you for an absolutely perfect stay. Please congratulate the team of employees for a job well done!
