The only downside which I'll state first is that it was a little smaller than I anticipated. This is with my understanding of typical room sizes in Tokyo and knowing they are generally smaller.
Overall the room was great! The location was amazing! Easy walk to the station, so much good food around, some of the best food I've ever had, convenient store across the street.
The washer and dryer was literally outside the door, I thought it was a laundromat near by but no, it's right in front of the door which was great.
I would definitely want to stay here again.
