Location next to a seriously busy six-lane road. I feared traffic noise to be a round the clock nightmare, however, with the window shut, it was in fact never a problem, probably courtesy of double glazing and proper insulation generally. The window could be opened wide, which was a welcome surprise, but the roar of the traffic (even on a 4th floor) was such that nobody would want to put up with it for longer than strictly necessary. The Kadoma area may appear rather underwhelming initially, but it is relatively convenient for the Expo Park (a major attraction by any standards) and more geared for local residents rather than commuters, who are another type of creature with different needs. No Metro station nearby, but it is on the intersection of the Osaka Monorail and the Keihan light railway. Otherwise, good predictable Toyoko with self-service check-in machine. Useful 7Eleven just opposite.
