What a perfect location! Most importantly, it was walking distance to Shinanomachi where I need to take my parents to visit culture centres and the min-on museum nearby. Simply, simply perfect!
From Narita airport, take the limousine bus to Hotel New Otani (instead of Shinjuku as it is nearer and away from the heavy human traffic). At the hotel, so many taxis to choose from and you arrived at the apartment within minutes.
Apartment is 3mins walk to Yotsuya Sanchome; a metro gateway to Shinjuku, Ginza, Tokyo stations and interconnection to JR lines. Surrounding the apartment are several affordable local food which will make you spoiled for choice; all within 3 to 5mins walk. Yumi recommended a sushi and sashimi place to eat and the food was authentic. I went three times! Also, few convenient shops nearby; 7-11, Family Mart, bakery, etc for you to choose as well. Portable wifi available for us to use indoor and outdoor. Our host Yumi took care of us very well. The apartment for us is cosy, neat for a family of 5 members. I would strongly recommend to anyone who desire a suburb break away from the bustling city. Thanks, Yumiko san, for making our stay comfortable and enjoyable!
