The room was large enough, the matrass was comfortable, but there were a few things that made me disappointed.
Overall, the apartment was not clean; many hairs on the blanket/pillows, in the bathtub, on the floor. In the two days I slept there, nothing was cleaned by the owner. Toilet and bathtub were dirty; water drainage in bathtub/shower wasn't good, dried up urine under toilet seat. If you're sharing one bathroom with 3 other rooms, the least the owner could do IMO is clean the bathroom and toilet on a daily basis.
The ventilation system in the utilities closet in the kitchen (next to room 4) was very loud and would turn on/off regularly.
It was very warm in the apartment/bedrooms (I prefer a cooler place to sleep in, without having to open the window too much). The provided blanket, however, was quiet thin. The bed in room 1 was slightly crooked (so was the entire floor/walls) so I slept with my head angled down (slightly lower than my feet).
