If you decide to book a stay at a 4-star hotel in Montecarlo, you'll usually find lots of conveniences to keep you comfortable, such as a gym, pool and restaurant. You can enjoy top-quality service and deluxe accommodations. Go for a 5-star hotel and you'll have access to a few extra perks — think concierge assistance, on-site spas and nightly turndown services. You'll most likely get extra amenities and exclusive services at a 5-star retreat, though both are superb options for luxury travelers.
