The hotel is not new but reasonably maintained. Mattresses are a a bit squeaky. Overall a clean place. We didn’t use the onsen. We came with a small baby. It was a rainy day. We appreciate it was an hour early for check in, and no problem with us. But showing the reception staff that there are no cars at all in the parking lots they still asked us to go away, park in a public car park, and come back to park at the time of check in. Rules may be rules, but really…? Eventually we parked, but when we drove out in the rain on our rerun found there was no longer parking for us, as we hadn’t reserved our spot, only paid. We found parking in the end, but why so complicated? Anyway, we do not recommend this hotel for guests with a car. Parking in Japan is relatively inexpensive and not complicated, except here.
The breakfast we also rate below average for both Asian and European standards, but not a deal breaker. Lots of other breakfast places nearby.
I seldom write such reviews. Otaru is a charming town and worth visiting.
