This place is just absolutely heavenly! We were there for three days with my sister and our husbands. We got a two bedroom chalet. The property is very new and hence everything is really nice and Phi Phi-Lux for a great price. All the chalets overlook the blue ocean. The beds were very comfortable and everything worked great (Air con, hot water etc.).
The staff is really lovely, especially Emmy and Biya. They helped us out with many recommendations as well as organized a half day boat trip around the nearby sights (Maya Bay, Monkey Bay etc.). In the late afternoon, the pool is a pleasure to hang out in.
The food was good, but comes in small quantities, so you'll be better off eating in the nearby village, as you'll typically be quite hungry from all the beaching.
The staff helped us out with laundry - you'll go through your clothes very quickly in Phi Phi, so it helped that they were willing to negotiate a per kilo price which does not include ironing, but is significantly more affordable than the laundry list price.
Location: From Tonsai pier, it takes about 20 minutes to get to Phi Phi Phu, so you're a bit far from the action. This worked well for us, but others might like to be closer to the hustle and bustle. There is a village with many restaurants and bars withing a short walk, and we had some of the best meals, drinks and music there.
