Osaka Castle is maybe 5-10 minutes walk from this place so you're not going to get much closer, which meant I could see the castle the same day I arrived, thus saving a day's sightseeing. The lobby and public areas of the hotel are very nice, and the staff were really helpful, even though I arrived early they cleaned my room in 15 minutes and let me in early which was really great of them. My room itself was really big as far as these things go, but maybe in need of some decorating as it was looking a bit tired but otherwise great. There's no wifi, only wired internet which meant I had to go out and get a cable but this was the only real downside. If you're not in town for long and want to see the castle, this is ideal, its also right above a subway stop so great links to other places. Breakfast is buffet style, so you can fill yourself up, worth getting!
