Only stayed one night for catching early flight from KIX. It provides free shuttle to KIX. Regular shuttle starts at 6:30, and they provide a special shuttle at 5:30. The bus driver is very nice - upon arriving, we wanted to read the signs to kill some time since we were too early, he thought we need help, and he did approach us to ask even he already seated in the bus.
The room is small, but enough for 4 people (same size as Daiichi hotel in Tokyo), but they don't allow me to book - I had to book two rooms for two adults and two children, kind of waste money.
