"This is a great place to stay in Osaka. The hotel is awesome. The rooms were comfortable but a tad bit small (compared to rooms I have been). The breakfast is very good, with a good mix of western and Japanese cuisines. We went with 2 kids and they really enjoyed their breakfast every day. Breakfast was served from 7 to 10, but the kitchen closes at 9:45am. We didn't have a single issue while we stayed there. Checkin is strictly at 3pm and checkout is 12pm.
The hotel provides Yamato service and it costed us approximately ¥2100 per cabin bag size suitcase. If you drop it off before 3pm, it will get dropped off by the next day.
There is a currency exchange machine by the check in counters. The currency exchange rate provided was not too bad $1:¥153 (at the machine) vs $1:163 (Google quote) on the day we used it.
The best thing is that if you go to the basement, you can directly enter Umeda station which is the primary way to get on to the osaka Subway line. But if you use the elevators to go to 2nd floor, you can walk to Osaka station, which allows you to use the JR lines. Very convenient.
Something else to note about this property, the hotel is on the 9th floor and goes up to 35th floor. The floors below is shopping (Daiso, Uniqlo, etc). There is a Yodabashi also in the complex. On the 8th floor they have a variety of dinning restaurants and tons more in the basement around the entry to the Umeda stn. We definitely recommend this location and will choose it on our next stay."
