Great location, 10 min walk from Takadanobaba station and accessible by JR line (if you have a JR pass). Enough room for two people, three would be a squish if you also had baggage. Pretty quiet, at the end of a street. Warm with heat pump.
Our main concern was the mould in many areas of the bathroom. It looked like it hadn’t been cleaned.
Bed was very comfortable and linen was clean
