I have stayed at Crowne Plaza twice during business trips and I have grown quite fond of it. It's a quiet, not overly pricey, clean business hotel with a gym, located in a posh area of Amsterdam. The hotel is close to Amsterdam Zuid train and metro station where you can reach Amsterdam Centraal and Schiphol Airport within 30 minutes.
The rooms are clean and modern with large windows and good soundproofing. The breakfast buffet is closed during COVID and is delivered to your room instead. The breakfast itself is a standard continental breakfast, a bit bland, their buffet selection was better. For takeaway food (lunch or dinner), I can recommend Sushito which is a 5 minutes walk from the hotel.
The service in this hotel is impeccable. I was offered a bag of tea, fresh milk, cookies and chocolate during check-in and had the opportunity to do a late checkout (2 PM) which allowed me to sleep in before going to the airport.
Overall, if you want a quiet and comfortable stay in Amsterdam, I can highly recommend this hotel.
