The novelty wore off early (around 9AM), getting there after a full day of travel, just wanting to crash. I could check-in, but couldn't stay until 3PM. They stored my bag while I zombie'd around town, but the novelty was quickly restored.
It has pretty much everything you *need*, with multiple amenities including a spa, sauna, sento (look up rules if unfamiliar), coin-operated laundry, charging cables, and lounge with free food/drink. Indoor smoking room, appears well ventilated, as I didn't note any smell around the property.
Overall, interesting, and recommended, all in a good location with friendly staff.
