Kimpton is a 5 min walk from Centraal. The location is incredible.
With Spire + Inner Circle, you will be looking at top tier benefits. The Kimpton recognised my IHG Plat status even before the integration. I was able to use my raid the bar benefit for a mimosa at the hotel breakfast.
Another nice perk - Kimpton has a complimentary wine/cheese hour. It does get busy as its open to all guests but still a good way to start the evening if you get there early. You will have to pay for Club access to enjoy the same at IC Amstel.
