Hotel Hot spring Hikari

The facilities were old, but the room was very clean. The staff at the front desk and in the dining area were very kind. I called the front desk to confirm check-in time, but they were short-staffed and did not answer, but other than that it was perfect. I stayed alone on business. My reservation for one person was not communicated, so I was charged the hot spring tax for two people. When I explained the situation, they corrected it to one person, but I would have liked them to respond more clearly based on the guest name at the time of booking. There is a problem with trip.com's reservation specifications and I would like them to improve it.
