We had a great time staying at this place. The owner is very helpful and give quick response to our questions. The place is not big but there is enough space for the three of us. The place is clean and provide amenities such as soap, towel, etc. It also has a kitchen with washing machine and microwave that we can use.
The location is close to akebonobashi station (less than five minutes walking) and two station away from shinjuku station. For those who travel with kids, this place is 10 mins away (by walking) from tokyo toy museum and fire museum. In addition to that, many restaurant and minimarket nearby.
