I was in London for 3 nights, the room was exactly what Azim describing. Everything was clean in the Room. In Addition, the Room was outside the Building in the basement, under the pavement (You will hear the persons on the pavement, quite noisy) For the toilet and the shower, you have to go into the main Building through the public.
The toilet and the shower are on the second floor in the main building in a very small room. ( in max. 1,5m², like a wall cupboard) For bigger persons, like me it wasn´t so easy to move inside…
For this price and the location near to the centre it is a very good offer, but does not expect too much luxury! I recommend this place for all people for a short stay!
