If you choose to book a stay at a 4-star hotel in Amsterdam, you'll typically find lots of conveniences to keep you comfortable, such as a gym, restaurant and pool. You can look forward to high-quality service and upscale accommodations. Pick a 5-star hotel and you'll get a few extra perks — think on-site spas, around-the-clock concierge and indulgent turndown services. You're likely to get additional amenities and first-class services at a 5-star getaway, but both are superb options for luxury travelers.
