We loved our stay at Zentis Osaka — the staff and atmosphere were warm and welcoming, the rooms are large and comfortable, and the amenities are excellent (the laundry room is not only functional but also chic, with a vending machine, Nespresso machine, microwave, sofa, perfumes, books etc). The hotel is a bit of a walk to the metro, but very easily accessible by taxi and on foot, and although there’s a lot of night life nearby, it’s a quiet location to stay in and the rooms are very quiet/comfortable for sleeping.
