Yuka's apartment was really lovely. My husband and I stayed there for 2 weeks and really enjoyed it. It's definitely on the smaller side, but it was perfect for two of us. My favorite part was the balcony––I sat there every morning––and Haruka Breads (the bakery on the ground floor of the building) was *amazing*!
There is a big freeway in front of the building, which is not the most pleasant, but once you start walking through the neighborhood it is really, really lovely. This is a more neighborhood-like area, and I loved that. If you're looking to stay right in the middle of a more hectic Tokyo neighborhood, this might not be the right area for you (though you are still only 2 stops away from Shinjuku and all of its sensory overload).
There lot of small delicious restaurants very close to the apartment.
We would definitely stay at Yuka's place again!
