Very Clean and Nice Amenities. Spacious and Tidy with the special touch of Japanese tradition. Hinoki bath was very nice experience. Overally this apartment is really good for comfortable family trip.
Only weaknesses are that there are not much restaurants nearby and it has no elevators. But metro station is very near and you can easily go to Shinjuku main street with 10 minutes walk.
Ryota's team is super. Really kind and response very quickly. Highly recommend if you want spacious place with adequate price.
