Hostel Kura is good value for money.
Check in/check out: I was greeted by the staff and shown around (to my assigned bed as well). I dropped off my stuff then went exploring because check in was later. Check out before 10am and all you need to do is write your bed number on a sheet of paper so they know which beds to clean.
Beds: I got a bed with a curtain that ran along the length of it (as opposed to just at the foot of it). I don't think option is captured in the pictures. Mattress was a bit thin but I might've just been super sore from days of exploring. You have your own little lamp and wall ports.
Security: Keypad lock to get through front door (accessing the common area and shared toilet) and another one (with a different code) on the door to the beds area. Small lockers (think of a shoebox) available for your passports etc. Storage under the beds.
Amenities: 1 shared toilet near outside common area, 1 female toilet and 1 male toilet in the beds area, 2 shared showers and 4 sinks in the bathroom of the beds area. Hair dryers and bathmats available. Towels available for hire.
Location: Very quiet area. Walking distance from Asakusa (Sensoji temple) and Ueno (Yokocho market). Check public transport to places you want to explore on Google maps to see if you're comfortable with it first. There's a FamilyMart as well as a self serve coin laundry around the corner. Some small restaurants around.
Rules: Lights on at 10am and off at 11pm. They ask that you keep noise to a minimum after 11pm.
Staff: Super friendly.
