Tower of the Sun Tours

The room was basic and clean. The main issue was that the air conditioning was disabled in the room. There was a sign in the room stating it was controlled across the whole hotel and I wouldn't be able to turn it on. It was quite humid in Osaka when I was visiting, and the lack of AC meant I had to keep the window open the tiny amount that was allowed. This made the primary purpose of the hotel to "Just Sleep" a bit more difficult than I would have liked. If you don't mind being a little warm and sweaty during the night, you might be okay. I found it difficult to sleep and get comfortable in the warm humid nights. I would suggest calling ahead to see if the air conditioning is allowed/enabled before making a trip to this hotel. Or perhaps only go in the cooler months.
