The staff was friendly without being overbearing. The beds were extremely comfortable, and the room was enormous! The location was perfect, right across the street from the beach, and near many restaurants.
The only thing to be aware of is that it is a older hotel. Aside from the beds, it does not have any modern sense of luxury. It does not seem shabby in any way and is kept very clean. The walls are quite thin, so if you are sensitive to noise that might be worth noting.
On a note that is just FYI: the private onsen pool connected to the room must have had the water pumped directly from the source because it was too hot to enter, and needed cold water to be added for quite some time before it was a tolerable temperature.
