We really enjoyed staying here - felt the location was awesome, the house was clean and comfortable, and we had zero issues at all.
We really liked that we could easily make breakfast and use the dishwasher, and also use the washing machine, which was also a drier. Heating was good (we came in winter) and bathroom was clean and good.
Appreciated the extra blankets, and overall we just had a great time here. Good location with regard to the train - it’s a nice walk to the train station, which can quickly take you to Shinjuku and you can go to basically anywhere from there. The accommodation itself is near convenience stores and a supermarket.
Really no complaints, and would highly recommend it for any groups like us (we had 6 people).
