Great house to stay, wonderful host.
Rumika was very easy to communicate with. The house is located 5 minutes walk away from the nearest train station, there are supermarkets and convenience store 2 minutes walk away. Everything essential was supplied, the host was very thoughtful and greeted us when we arrive on check in.
The washing machine and dryer are so helpful during our stay, Rumika kindly supplied laundry liquid and softener.
I would definitely recommend Rumika's house to all travellers who is looking for a big house to stay near the Shinjuku area.
