The room was ok, a bit smaller than we expected. We were given a room on the 3rd floor which has low ceiling and feels even tighter. The shower pressure is extremely low, it literally just drips water, and the window wouldn't stay open by itself, we had to put a bottle there to hold it.
If this was a room in a family home I wouldn't be so harsh with criticism but this is clearly a company that owns the whole building and rents out rooms for profit, basically a hotel. So for hotel standards and for this price, even if it's in London, I expected a bit more.
