The front desk staff were friendly, helpful and fluent in English communication. This apartment is definitely family- and infant-friendly, and I really appreciated that the bedroom was separated from the living area and pantry (no stove/cooking equipment) —it made things much more comfortable with a baby. The location is also convenient, with train stations nearby that made exploring Osaka easy.
The only downsides were that the laundry and dryer facilities are located at the reception area instead of in-room, and there were occasional stomping noises from the room above. However, aside from these minor issues, I would still highly recommend this hotel for families.
