I would stay at JM again, but wouldn't be enthusiastic about it.
JM is kind of a weird hotel in that I saw the cleaner crew. I stayed there four nights, and except for Sunday, I saw the cleaning people every day. I think they started work around 9:00 am and were still around after 1:00 pm. Yet my room was still oddly not clean. What makes JM rooms feel unclean is that when you first walk in, you're quite surprised at how clean it "looks". But then, as another reviewer said, you start noticing things, like black hairs on the white blankets. Hairs left on the sink. Old, old crumbs on the desk. Stains on the walls.
Besides the stains on the wall, the other issues could, and should, be taken care of. But JM is a bit cheap, being around 40 to 50 dollars a night, placing it in the love motel bracket. And if you're just staying there for a night, then it's far above other love motels on the island. And I get the feeling that's exactly what they're going for. A love motel that's slightly above other love motels in the area.
I was happy to leave JM, but for the price in that part of the city, I would stay again. I just think that if they're paying the cleaning crew, they might as well get their money's worth and make sure the workers actually clean the rooms.
