Here’s a more polished and balanced version of your Trip.com review:
We stayed at Casa De Mar in a Deluxe Villa. Overall, it’s a good place to stay, but I don’t think the villa is worth the extra cost. The standard rooms should be more than enough for most guests.
The breakfast is decent, but don’t expect a huge variety. One issue is that there doesn’t seem to be proper refrigeration for items like butter, yogurt, juices, and water. If you arrive after 8:00 AM, some items—especially the butter and cheese—can look melted, and the yogurt is very sweet and not served cold. On the positive side, there is a good selection of freshly cooked eggs and bread.
The beach in front of the hotel isn’t ideal for swimming because it’s very shallow. However, the location is peaceful, and the hotel is still a good base for exploring Koh Samui.
Overall, I enjoyed my stay, but I would recommend booking a standard room instead of paying extra for a villa.
