Yuka's place was just as pictured. Small, but spotless and efficiently stocked. We took advantage of the free portable wifi and laundry machine for our one week stay. Yuka and team were also fantastic communicators that periodically checked in with us despite the holidays.
The only minor downsides are the mattress is a bit thin and the apt is a couple of transfers away from major attractions. But, it's within a few blocks of Hatagaya station!
