If you choose to book a stay at a 4-star hotel in Roslyn, you'll typically find plenty of amenities to ensure you're comfortable, such as a gym, pool and restaurant. You can look forward to excellent service and upmarket surroundings. Pick a 5-star hotel and you'll have access to a few extra bells and whistles — think on-site spas, 24-hour front desk and nightly turndown services. You're likely to get more amenities and premium services at a 5-star getaway, though both are awesome options for luxury travelers.
