If you choose to stay at a 4-star hotel in Volga, you'll usually find plenty of amenities to keep you relaxed, such as a restaurant, gym and pool. You can experience excellent service and upmarket accommodations. Go for 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 indulgent turndown services. You're likely to get additional amenities and premium services at a 5-star stay, but both are fabulous options for luxury guests.
