I stayed at Kannell's B&B for about a week. It was sparkling clean with perfect location. So close to tubes, UCL, SOAS, LSE and many other university. The room was small and cozy. The communication and response were so quick and polite. Despite the misunderstanding from side they replied in a very understanding and nice way. Self check-in was great. The only thing is that the room was a bit noisy cause it was close to tube but it was ok.
The overall rate was very good. I would recommend it if u r looking for a central location close to universities and tubes and a clean place :)
