Pros (+) Only a few steps from the subway, Hotel Sun White is a good base for exploring Osaka. The staff was very friendly and helpful. Our room was very clean, new towels and amenities were left daily, and it had a decent-sized fridge.
Cons (-) Rooms are very small, with not a lot of storage space, and anyone over 6 feet (185cm) won't be able to stand up in the shower. The windows don't open so it can get a little stuffy, but there's A/C.
