Everywhere is super clean and the personnel is very polite, patient, and helpful even for international guests (they speak English and on the reception desk they have a microphone and a screen that translates on real time).
They have shampoo, conditioner, soap, face and handwash, hairdrier, hair straightener and curler, makeup remover and its pads. Every guest is given a basket with a body towel, face towel, and foot towel (for the shower), and a pijama. You can change the basket every morning and receive a clean new one on the reception. This helps the ones who wish to pack light.
The location is near loads of food places and even Dotonbori. If I go to Osaka again i'm pretty sure I would stay here again as well.
