Booked a double-room for 2 of us for a week.
Hotel building itself is old but the rooms are spotless and the sheets and towels are all clean. Staff were always ready to help and were really friendly.
We had a kitchenette which was handy for cooking, but the general store downstairs had so many food options (bento boxes, sushi, poke bowls, full bakery) at really cheap prices (6 USD or less).
If you need to be surrounded by fancy new furnishings and chain-smoking package tourists then maybe try the bigger hotels nearby.
If you want clean, breezy rooms with helpful staff and cheap, high-quality food, Himawari is a solid option
