Great location - The hotel is located on the prettiest end of Jaco Beach - away from the town's center but within easy walking distance (about a 20 minute stroll by beach to get to the shops and bars).
Rooms - The rooms are very clean and comfortable, beautifully decorated with a tropical vibe. The daily cleaning service does an excellent, thorough job. I would have felt more secure with electronic key card swipe locks (rather then the old fashioned key locks), but the hotel grounds in general feel very safe and secure.
Pool - The pool is one of the nicest hotel pools I've seen at a hotel - the majority of the pool is four feet or deeper, perfect for adults. It is kept at a warm temperature and well maintained. It was never crowded and always peaceful.
Grounds/Landscaping - The hotel area is kept very nice - not overly manicured, but still green and lush with plenty of colorful flowers.
Restaurant/Bar - Everything we ate at the hotel was delicious - the kitchen does a great job of preparing tasty dishes. The service is also worth mentioning - very attentive and quick to help and serve you.
I would recommend this hotel to anybody looking for a gorgeous, peaceful place to stay on Jaco Beach. My only advice is to triple check all of your reservations with the hotel (room reservations, transportation, excursions, etc.) My husband and I stayed at this hotel with our family and friends when we got married in February. We had wedding guests stay in six other rooms. Though the hotel did a great job accommodating everybody else, we were disappointed that del Mar had lost OUR reservation, which had been made and confirmed nine months previously. After printing out my correspondence with the front desk and my reservation form, the hotel put us in the penthouse (at a reduced rate) and then moved us to another room for the remaining eight nights. Days away from my wedding and stressed from traveling, this incident had made me extremely anxious about how our other wedding guests reservations would be handled. Fortunately, only one other guests' reservations were mismanaged and the hotel made up for the inconvenience and unnecessary stress that it had caused. The issue with the reservations aside, I am glad we chose to stay here with our friends and family - it is on a gorgeous beach and is a very well kept hotel. Be sure to confirm your reservations and make sure that all communications with the front desk are clear and understood.
