I Lived somewhere similar for six months, as a transition from rooms in flatshares to renting a proper flat on my own. It was shit, but I knew it was only for six months. I had boxes of stuff piled up everywhere, no storage space. It was very very damp and freezing cold. I wouldn’t let anyone visit me there!
The plus points were it was cheap and very close to work! But I was delighted to leave it to move to a proper flat “I have walls! And rooms! I can walk from room to room!”
