This is a great place for a budget stay! The standard bedroom felt a little tiny even as a solo traveler, so I would recommend going for the double if you are traveling as a duo or feel you need more space.
The Japanese breakfast is very much what it says on the card—if you're a foreigner and can't read hiragana/katakana, you might not recognize much beyond eggs/rice/pastries.
The front desk staff were very receptive and kind! All in all I very much enjoyed my stay, especially with Tojinmachi Station just outside the door. It made traveling around the city super easy.
