I had a wonderful stay here. If you don't mind having to use a shared bathroom (which there are 2 of them) and most care about a central London stay that's also very affordable, this is the perfect spot! It's a small room, but if you don't mind and pretty much only need a bed to crash on and a safe area to leave your bags, then look no further!
Hong was extremely responsive. The only thing that was lacking for me was a power adapter for other European countries and he dropped it off for me the following day.
One thing is that it can be a bit noisy at night, but either close the window or use ear plugs if you need quiet. Highly recommend...
