I had a great stay at this place. The locations is very convenient for traveling around Tokyo since it's nearly directly at the Sugamo station from which you can access the JR Yamanote loop line. The room itself is generally clean though I wouldn't say spotless. The washing machine and dryer in the basement are very convenient for longer stays. All the listed amenities were provided though the internet can get throttled if you have larger data volume requirements. (believe it's a mobile contract with a data cap) All in all if you don't have very high demands for your accommodation this place is a quite reasonably priced option for staying in Tokyo.
