Park Central Sakura Hotel was perfect for the purpose of our 3-night stay. Check-in process was straightforward and the staff were clear in their instructions. The room is quite small, but since we spent our days out doing activities and seeing sights we didn't mind. Otherwise, the room was clean and quiet, the bed comfortable, the bed full of amenities and very clean, and the desk was useful to have even a small area to place our things. There was also a mini-fridge and kettle in the room, though eating/drinking in the room was discouraged. If you do want to eat at the hotel, there is a recreation/dining room on one of the floors with plenty of tables and chairs. The location worked well for using the metro lines frequently, and we felt very safe in the neighbourhood. Would definitely stay again if finding ourselves in Osaka!
