I've stayed Dorm room for 4nights. Was totally recommendable.
I had every breakfast at nice lounge also beer for some nights.
Room was fine but there are just mattress but no beds as you seen in the picture. You also have free bath towel and free bottle of water and free toothbrush and paste as amenities.
AC was working pretty well and also the room has some fans so you can spend comfy nights.
The hostel offers bicycles for rent 1$/d. Some of them were nearly broken but you can choose fine one if you depart the hostel earlier. I used those bicycles for wandering all around Angkor vat.
