Here's what the latest reviewer of the Andara had to say on February 22. The resort is at Kamala, high on the hills, quite some distance from Kamala beach:
''We originally booked a 4 night stay here based upon strong reviews, etc. Well, we ended up absolutely loving Andara and booked for an additional 4 nights (canceling a reservation at another property).
''There are properties/resorts that are better situated ON the beach with unobstructed ocean views of course, but that was more than made up for by the property and suites/villas themselves.
''It was truly as though we were staying in a beautiful home complete with every needed amenity, including our own plunge pool.
''The sense of tranquility and relaxation was prevalent throughout the property. The staff, the decor, the manager, the food, the service, bath amenities, transportation... EVERYTHING was excellent.
''We look forward to returning to Andara soon!
''The only note of disappointment I'd make is to point out that the Beach Club is really just a few white day beds amongst a crowded beach, surrounded with a lot of activity.
''The beach hawkers selling everything under the sun come right up to your day bed, without the staff doing much about it. This was a bit annoying after awhile.
''We ended up preferring the Andara main pool or our plunge pool over the 'Beach Club'. On the plus side, a bucket of ice cold bottles of water and wi-fi are available from the staff.''
