Great location. About 3 minutes from Shibuya station. The internet seems fast enough and the room was very clean and well organized.
The only cons I can think of is that there were no instructions for the Japanese washing machine, however using a camera translation app helped (the machine washes and dries). Also, the blinds in the bedroom does in some light in the morning. This didn't bother me, but something to consider.
Lastly, I noticed there were a lot of baby item, such as a stroller and high chairs. We didn't use it, but kind of nice to see.
