JW Marriott Kolkata is a luxurious property with a great location and connectivity. The staff is well-cultured, cheerful, and accommodating. The food is delicious, especially the regional Bengali fish. The decor is beautiful, and the rooftop pool offers stunning views. The rooms are plush and well-maintained. The staff's attention to detail and commitment to going above and beyond is commendable. However, some guests found the breakfast buffet limited, and the food quality needs improvement. Overall, it's a great property for a luxurious staycation.
