We did not meet Yuka during our short stay but she did everything within her means to make our arrival as smooth as possible.
The apartment is exactly as shown in pictures, literally a five minute walk from the train station. Wifi was down before we checked in and she provided a portable one for our use. View from apartment is not great and facing a highway, so I'd agree with other reviewers that is can be a little noisy at times but it is not within Yuka's control.
Overall it was a pleasant stay.
