Machiko's place was ok. Place was sparkling clean, had everything we needed, and location was convenient in the heart of Shinjuku within walking distance to lots of food and shopping. Unfortunately during our stay we had a major issue with the hot water, with the water randomly shutting off and only reaching lukewarm temperatures. This was quite annoying as it was still cold when we visited. We contacted Machiko and she was quick to send someone over the next day to check out the issue, but unfortunately the issue couldn't be fixed during our stay (we stayed 3 nights and she sent someone over twice). She did apologize and left us strawberries which was nice. I would give her place another chance and try it again if the water could be fixed. None of the other reviews mention this issue so perhaps we were just unlucky. Water pressure was also a bit weak but we experienced this issue in all the airbnbs we stayed at in Japan. The bed was small but we found it quite comfortable. We did not use the internet as we had our own wifi egg so can't comment on speed. Overall we enjoyed our stay and aside from the hot water issue I would recommend the apartment.
