If you choose to spend your vacation at a 4-star hotel in Kachevan, you'll usually find plenty of conveniences to make sure you're comfortable, such as a gym, pool and restaurant. You can look forward to excellent service and upscale surroundings. Pick a 5-star hotel and you'll have access to a few extra bells and whistles — think around-the-clock concierge, on-site spas and opulent turndown services. You're likely to get more amenities and first-class services at a 5-star getaway, but both are fabulous options for luxury guests.
