I used the place for 24 in a short trip to London.
Pros: good price, very clean, position (central and 2 mins walking to metro).
The place is BASIC: towel available for extra fee, there are 4 bedrooms in total, one bathroom only. But as I said the place is VERY clean, I think on a daily basis.
Overall you get what you pay for and overall this was a very good experience.
