Min and Haru should have some kind of Extra Special Superhero Host title. Im a superhost myself and learned a lot from them. They genuinely care about their guests, and take care of them. They are by far the best hosts I've ever stayed with.
The room feels spacious because of the huge windows, which have great night time views. There's a spacious closet and full length mirror near the door and a little shelf above the bed for your phone etc
The bathroom toilet and washing machine are on the next floor down, along with the common room kitchen, and there are usually a few other guests to chat with and get tips and advice from.
There are also rooms with several beds, so a family could stay, and 2 tatami mat rooms
I wish I'd stayed here when I first arrived and will definitely stay again on my next trip!
