I stayed at Ya Nui Resort (1, not 2!) for a month from mid-July to mid-August. I was greeted by Gabriel the owner when I arrived even though it was after midnight and was shown to my room without having to deal with check-in until morning. Reception took care of everything from booking a motorbike for the month (at an excellent rate) to airport transfers to directions and more. The staff are the friendliest people I've ever met and I was so sad I had to say goodbye at the end of my stay!
The pool is lovely and always immaculate. My room was always clean as well and if I needed anything, like extra blankets or pillows, I got it within minutes.
The restaurant attached is superb as well. The owners are also very sweet and accommodating, and the food was the best in town, no exaggeration! The prices were very competitive as well. The Wednesday night BBQ's are deeply missed on my end. The owner/chef will open early if you ask and will accommodate any alteration to the extensive menu that you request.
I had an amazing stay and would do it all over again in a heart-beat!
Oh, and the prices are VERY competitive, and the value cannot be beat.
