I visited Muzaffarabad, Kutton, Neelum, Upper Neelum, Keran, Sharda, Kel etc this year June. Trust me it was my biggest mistake to plan a visit for it. I hardly spent 2 days & 2 nights at AJK and rush to Naran to actually enjoy my vacations.
No electricity, no mobile.network, no clear water, no basic necessities, no good roads network, hours of tiring drive to reach to any other spot.
The only attraction people feel to visit Kashmir is to see indian occupied part of it, & you cant see even a 'bakri ka bacha' on the other side.
Your cost will be for fuel only, rooms and food is very cheap there. You can have a room as low as Rs. 2000 at Upper Neelum.
If you wish to stay at Sharda one night then you have to make an advance booking from Muzaffarabad. No light at Sharda also & only black water comes out of taps
