Room: even better than in their photos with a lot of perks (4G phone you can take out, a massage pillow, etc). Very comfortable and just enough space for 1 person.
Service: the staff was really helpful from the cleaning lady, who opened the door right after I closed it with my key inside, to the front desk employees, who diligently answered my questions. Not having to worry about breakfast was definitely a relief and their options should fit most people's taste. Last but not least, the hotel is well located. Close enough to walk easily to 2 subway stations with 1 being a mega-hub in Osaka's public transportation system.
