Great location for travelling to all the sights, 7 minutes flat walk to the station, which was a bit long for me as I have knee trouble, but it is then only 1 stop to Shinjinku, which has lines that take you all over Tokyo. ( take care not to come out of the wrong exit as this adds a good 3 -4 minutes to the walk home, you need south, and only central and east exits are prominently marked, so head to the central and you will find the south exit) The local area has great supermarkets and restaurants. This is a great area to feel like a local as it is not touristy at all, and yet in a very short time you are in the middle of it all.
My son slept on the sofa bed as he was more comfortable there and there was plenty of spare linen for this.
Roof balcony is a great space to sit outside.
Really recommend this as a base for seeing the whole of Tokyo. We were 6 adults and one toddler and it was a great space for us. Communication with Kevin was superb, easy and always very prompt.
The house has the basics you will need except for cooking. Only very basic utensils and pans are supplied. But as I said there a great tasty cheap restaurants in a short walk.
