Sonar Bangla Resort is a budget-friendly property located near the beach in Mandarmani. The staff is friendly and polite, and the food is delicious. The rooms are spacious and clean, with comfortable beds. The property has a private beach access and a garden for organic farming. However, the property is still under construction, and some areas are not well-maintained. The bathroom needs renovation, and the TV and other amenities are not up to the mark. The swimming pool is not yet operational. Overall, it's a decent property for a budget stay.
