This apartment in Shibuya was fine as a place to get some sleep, but it suffered from a few issues that prevent me from recommending it to other travelers. On the plus side, the location was very convenient to Shibuya station, the apartment was clean, and there was a thorough handbook explaining pretty much everything we needed to know about our stay. The host was also very friendly and responsive.
However, there were a number of downsides to this apartment. For one, it is very close to the adult entertainment district of Shibuya, and I wish we knew about this beforehand. It was uncomfortable walking through there on our way to the train station, and we were propositioned for services multiple times.
As for the apartment itself, there was a constant, odd smell from the bathroom that really bothered me. I'm not sure what it was, but it was unpleasant. Also, the window did not insulate the apartment from outside very well. It was often hard to sleep, especially on the weekend, due to loud street noise, to the point where it felt like the window had been left open.
Overall, I would find a different place if I were to stay in Shibuya again due to these downsides.
