hotel androoms was a great hotel when we based ourselves in Osaka.
Loved it for:
-Laundry room, reception will also hold your laundry if you cannot pick it up in time
-Clean and aesthetic rooms. They are very homely and I loved the format, which gave great sitting/table space to rest in. It is a great use of the typically small space in Japan hotels
-<5 min walk from Hommachi Stn (including the accessible elevator exit 2). Conveniently on Midosuji line and close to popular tourist areas such as Dotonbori and Shinsaibashi
-Staff were all kind and lovely, and the hotel is very comfortable and welcoming
Only negative is that it is unlikely you will get a window room with natural sunlight, so that may bother you if you spend a lot of time indoors/think natural light is important in your hotel room.
Overall really loved my stay here, cannot recommend enough if you want to stay in Osaka. I would definitely stay here again.
