We stayed 10 days at Kasalong Phuket resort from Dec 28th, 07 to Jan 7th 2008. we are a couple with no kids.
The hotel is nice, rooms are big enough and the staff is adorable and very helpful.
Located in the North east part of the island (5 minutes south from the airport but without the inconvenience of the planes), the nearest beach is Nai Yang. This is a local beach with bars and restaurants directly in the sand. We went to Patong and really prefered the good and cool ambiance of Nai Yang beach.
We highly recommend Kasalong for his friendly staff, it was really as confortable as home.

Quiet small resort in a tiny village next to Pearl village and a mini supermarket, 10mn drive to airport and 5mn drive to Nai Yang beach. Walking to the beach would take 20mn. Nai Yang beach is not very pleasant with all kind of bugs, dirt and mazout and no shade. There are some cheap restaurants. We prefered Naithon beach further south (10mn drive 200 baht one way) which is beautiful and clean, whith white sand and clear water (watch out the waves !). Resort is OK, houses face each other, suite was small but clean, balcony not really pleasant. Swimming pool is small and a bit dirty even though water was clear. Restaurant is eatable, selection is limited and service mediocre, but where else to eat ? We were the unique customers for about 8 completely unhelpful staff people. Poor english speaking. They charged us the extra bed even though it said on their website it was complimentary for children. We would not come back.
