Stayed in the 2 bed private, and it was perfect. Great hostel, nice staff, and it was a great location in the center of the city!
One of the best hostels I have ever stayed in. They have pretty much everything you need for a nice stay in London! A bar (where you can also order food), a nice lounge, laundry room, and lovely rooms with curtains around each bed. It was a bit of a walk to the center of the city, but it didn't bother us at all as you can take the bus or metro if you prefer.
The room was a great for what we needed it for! It was a good home base to sleep since we were out in the city all day. The room, shower, and bathroom were clean. The location wasn't the greatest, but there is a metro stop basically right in front of the hostel so you to get around easily anyways!
