I'm renting my futon couch bed in my small studio (24m2). You can find breakfast in the fridge and do laundry in laundry room - all included! Also towels, soap, etc. included. If I'm at home I'll share the the living room with you and during the night time I'm in my loft bed - or I might as well be out.
Ps. I hope you don't mind that I have terrarium with a small snake as a roommate - he is not very social and is only staying in his terrarium so probably you're not going to even notice him.
