Kei’s place is down the hill, 8-10 mins walk from Takadanobaba station.
Takadanobaba station is just several station away from Harajuku, Shinjuku ( 2 station ) and Shibuya, Asakusa, all other main points. It has some metros and JR too. Really2 convenient.
I really like walking along there because there are many shops, laundry shop, supermarkets, restaurants, convenient stores, tax free drugstores, fast food joints.
Amenities : Has all basic amenities. Has bath tub too if u need a hot bath. No hot seat for the toilet but only problem for us because its winter now. Has cooking ware and utensils if u need to cook. Supermarkets here are really cheap too.
Overall i would give 7/10. I booked quite last minute with an affordable price and couldn’t complaint much. It’s not the most advanced room like most in Japan but Its a great base area and really quiet.
