Aoa brother. Batakundi is 15 KM but 45 mins drive due to terrain. You may get earlier but all depend on traffic and road condition. There is no communication available from Nara onwards till Chilas, no cell phone and no landline either so please take this into account.
First hotel you get in batakundi sea side guest house. Mr shahid the manager is very helpful and accommodating. I stayed there with my family in fully furnished room for 6,000 on 29 June last week. You may get same room on cheap rate if you reach earlier. Next one is New lalazar. You may get room for 3-4000 Rs without any trouble. Location and hotels are comfortable and nearest to main road.
