We stayed for a week and found the room to be clean and comfortable. We had no problems with noise; the step up into the bathroom is important for travelers to know about, but it caused us no inconvenience. There's a nice deep bathtub as well as a shower. The room is not spacious, but our experience has been that Japanese hotel rooms in densely urban areas are seldom spacious. The lobby area is friendly, and one or another of us spent a little time there when we needed more space.
The one big minus for us and the reason I wouldn't give the hotel 5 stars was the wifi. This wouldn't be an issue for people who buy their own wifi, but we had gotten along fine with international roaming for data in our previous travels in Japan and had counted on the advertised wifi at our hotels to supplement it. The wifi at the hotel isn't password protected, so it isn't at all secure, and the signal strength is poor. We had to go to the lobby to do any substantial downloading or uploading, and we were reluctant to do anything confidential like check our bank balance back home.
The staff was friendly - we put no special demands on them, but the front desk was always well-staffed and there appeared to be plenty of help if it was needed.
The hotel's greatest asset is its location. Its entrance is on a quiet side street - our room actually overlooked the grounds of a nearby temple. However, it's in the middle of a lively district with restaurants and shopping (at various price levels - it would be possible to order a tailored suit OR buy t-shirts nearby; one could also eat modest or upscale meals). So the hotel was not loud, in our experience, but many lively options were in walking distance.
We found ourselves walking and relying on buses mainly (vs. in Tokyo, where the subway system is a little more comprehensive), and the location was very good for that (also for the subway, if we had used it more).
