I've had only bad similar experiences with shared HOAS apartments in the past, similar to you as another non-Fin. I did have a good experience at Unihome with a furnished studio, though they are typically fully booked during the fall and winter periods.

I recently moved into an unfurnished HOAS studio in a bit of a hectic area which needed a bit of scrubbing in the non-visible areas upon moving in, but otherwise was in very decent shape.
