We had some pleasant nights at Just Sleep Osaka. The area was quiet but still lots of variety of restaurants to choose from. The hotel is very close to Family Mart and 7-11 which is great.
However, the room is quite small even for Japan standard. Could only been able to open one big luggage in the room when it’s fully occupied by two adults.
The staff there was nice and friendly. They helped us called restaurants for reservations so that was greatly appreciated!
