Pre-booking questions are all thru Hotels.com messaging. On check in day the hotels.com message link disappeared so I guess you use the hotel direct contact. No live phone#, the hotel responds within 5-10 min. After you book, they’ll give you their booking website with phone#/contact info but I did not have to use them. On this website, the hotel will give you key code to get in the property and confirmation # to activate your room key. Everything is automated. I was lucky to see a staff while check in at noon (she let me keep my bag in the office while sightsee). If you check in outside business hours, don’t expect to see a live person. Hotels.com had section to notify estimate arrival time to the property so this may be why she was there when I arrived. Check in process was a breeze. All with iPad with simple instruction.The room was exceptional. kitchenette, clean bathroom, separate toilet. Hot water heater is Japanese specific so if you are not familiar with how to turn on, which is simple, you’ll have no hot water. 3 parking spot but seems to require pre registration. 3 min walk from the Osaka-Ko subway station, 5 min to Aquarium and Lego Discovery center. Many restaurants, 24 hr store. Surrounded by residential apartment bldg, felt pretty safe. Quiet. Perfect with family and kids. Thank you for the great stay!!
