Yuko place are awesome!
We love the house and we love the location. Its authentic Japanese house , with a slide doors, wooden flors and futon bed.
Location is also perfect, house is betwen Ikebukuro station and Mejiro station, so very close to the Yamanota line. If you want the hectic tokyo city seting just walk to Ikebukuro . If you want the more quiet location just walk and explore Mejiro.
The only negatives we have is the train noise. The first day we heard it a lot, but after 2 or 3 days stays we dont have any problem at al.
