Stayed in Double Room B for one night with my husband. The location was great—close to the subway, Tokyo Station, and convenience stores. One staff member, though not fluent in English, was very friendly and helpful, using a translator to assist us with our luggage delivery.
We had a carry-on and checked luggage, and the room still had plenty of space. I deducted one star due to a stain on the duvet cover (seemed like dried blood), but since we were only staying for one night and were tired from our flight, we didn't notify the staff.
