If you choose to book a stay at a 4-star hotel in Iacu, you'll usually find lots of amenities to ensure you're relaxed, such as a gym, pool and restaurant. You can experience excellent service and upscale accommodations. Choose a 5-star hotel and you'll get a few more bells and whistles — 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, though both are superb options for luxury guests.
