Which hostel at Taitou-ku, Tokyo, Japan is better?

Question:

I'm deciding to stay at the hostel for 4 days while visiting Tokyo. I cannot decide which one is the best hostel to stay since most of the review on each of them are good enough. There are 4 choices:

1) Palace Japan (http://www.palace-japan.com/english/index.html)
2) Khaosan Tokyo Original (http://www.khaosan-tokyo.com/en/original/)
3) Khaosan Tokyo Kabuki (http://www.khaosan-tokyo.com/en/kabuki/)
4) K's House Tokyo (http://kshouse.jp/tokyo-e/facilities/index.html)

Answer:

K's House Tokyo :)
Stayed here for about a week and the people were really friendly and the bathrooms were clean.
Free drink nights were hilarious!
