"We love the in-unit onsen and spa - they are constantly running and always hot!!! We can dip in any time with complete privacy. The Onsen is set up next to the balcony semi-outdoors with full length windows - therefore it is bright and sunny. The kitchen and the room tatami set up is great. The welcome drinks in the fridge are so nice! The appliances are smart. I wished there were a few more pods of coffee. I wished the check-in was not so difficult. We were only given the room key but not the room number. We stayed in the lobby by ourselves for like an hour to check 4 people in with our passport uploading and such. Then had to call the support line to get the room number. Wished to have done it in our room as promised. Other than that, it was great. We figured out we could walk to 7-11 to purchase prepped meals and frozen groceries to cook. The walk of 13 minutes along the sidewalk were a bit scary. Wished there were stairs along the hills because the stores are literally two curves above straight shot access if there were hillside stairs for shortcut. We also figured out the back ally of the building had a sliding door entrance - it could saved us the walking of a curve on the narrow road. Overall, it was an amazing facility. It is totally worth the trouble for two days of stay, 3 days would be excellent, but 1 day would not be worth the learning curve. I would come back for a 3-day stay next time instead of 2."
