I stayed in Tailana in end of June 2015.
There is currently a very small resort with 5 or 6 bungalows, each welcoming at least 2 people. The place is run by 3 locals who are quite nice.
The price for the accommodation is 100'000 IDR. If you want food (3 meals per day) & drinks (soft) included, then add another 100'000 IDR per person. So for 2 people in a single bungalow, count a total of 300'000 IDR.
The bungalows are quite nice, although very simple. There was no moskitos when I stayed there. Bring a lock if you want to lock your bungalow btw. There is no electricity in the bungalows, but there is electricity in the common area of the resort (cafe/dining-room/kitchen) if you want to power up your devices. There are no toilets nor showers in the bungalows, these are shared. There is no drinkable water in the island, but there is a well where water is used for everything except drinking.
Food & drinks: drinkable water & most of the food is imported from nearby islands. Fishes are fished by one of the guys running the place (you can join him btw). Coconuts are from the island.
You can contact Hermann if you want to book facebook.com/herman.pbb.9, he is one of the 3 guys running the place.
