Allthough it is quite small, it really fitted my needs perfectly and because of that the room did not feel that small to me. Located in the middle of Brixton, which I loved very much, yet inside the building it was really quiet so you could sleep well. It did not bother me, since I wasn't carrying much luggage with me, but be aware you will not have a closet to store clothes e.g.
I would recommend this room anytime if you are a solo traveller and would like to have some private space during a trip to London!
