If you choose to book a stay at a 4-star hotel in Limerick, you'll usually find loads of conveniences to make sure you're comfortable, such as a pool, restaurant and gym. You can enjoy excellent service and upscale surroundings. Pick a 5-star hotel and you'll get a few more perks — think around-the-clock concierge, on-site spas and opulent turndown services. You're likely to get more amenities and first-rate services at a 5-star getaway, but both are terrific options for luxury travelers.
