Booked on the advice of the guidebook. This was indeed a very friendly place and staff couldn’t have been more helpful. Found our room a little bit different from standard hotels (this was why we booked). Tatami mats were perfectly fine and room was large and airy. Onsen on the top floor was a bonus. Great view of river and right in the middle of nightlife area. Doors close at 1 but plenty of fun can be had before then.
Stayed at Kaneyoshi Ryokan, Namba Dotombori, Osaka.
