We stayed here for 3D2N. Location of the place is excellent as it's right smack in the middle of Dotonbori/Namba area. The only downside is is it's maybe a bit of a distance to walk from the nearest train station especially if you're lugging a lot of bags. (we alighted at Namba on the Midosuji Line). The staff can speak English and check-in was really smooth. We got the Japanese style room for 2 people and compared to other places in Japan, this one was really spacious. Everything was super clean. Hot water and Ice water was served to us every day along with some snacks. We didn't opt for the meals, so couldn't comment. They had a really cool heated mirror so it doesn't get fogged up after a hot shower and that fancy toilet too. The bath products were Shiseido and it really helped with my dry skin (went in Autumn). They also have a small gender-separated communal bath for use. The wi-fi in our room was weak though. :( Other than that we had everything we needed for a pleasant stay. (You can change into provided Yukatas while lounging in your room) Loved my stay - excellent location, service, rooms.
Stayed at Kaneyoshi Ryokan, Namba Dotombori, Osaka.
