The hotel is near subway train station where it helps convenient in travel. There is no JR station nearby, therefore, need to travel to other station for JR trains. The hotel room is clean, but the room is small for two people to move at the same time. The queen sized bed is big enough for two. It is not much of the concern on the room space as I have expected a small room space 13 sq m during booking.
The hotel uses central air con to manage the room temperature. It was early spring with temperature 12 to 20c. The hotel air con was running heater. The room was too warm for us to sleep at night that we have opened window to cool the room. We needed to bear the outside noise after opening the window. We have feedback the heater issue to the front desk but they were unable to help. The front desk has suggested us to rent a fan with fee or open the window. The air con(heater) has really disappointed us for our stay at Nest Hotel Osaka Shinsaibashi.
