The Jakarts Digial Hotel was a good inexpensive place to get a shower and relatively comfortable rest. Before staying i recommend you set your expectations appropriately. The pros out weighed the cons for me, I will stay there again.
Pros:
1) Inexpensive
2) Conveniently located in Terminal 3
3) Clean and realtively comfortable place to get a few hours sleep between flights
4) Relatively clean bathroom/shower (these are shared bathroom so will not be as clean as you would normally expect in a regular hotel.
5) Luggage storage.
6) Keycard access to pods, locker, and bathroom.
7) Plenty of room in the pod for me and my backpack (I'm 5' 7")
Cons:
1) Pods are just plastic containers with no insulation. Be prepared, you will hear other people coming and going. Prople were pretty quiet for my stay but you could still here doors/lockers opening and closing through out the night.
2) Units do not have individual aircons. They have fans that pull cool air into the pod from the surrounding room. The room is kept pretty cool but the pod maybe a bit warm to your liking.
