Kim's place was absolutely great, and right in the heart of our favourite little pocket of Tokyo.
The communication was great throughout, and Kim was incredibly helpful and responsive to any questions we had. Although we weren't on the 9th floor as the listing described the view was still very nice and the apartment is very easy to get to and rather spacious compared to other places in that area.
The only things we'd note as travellers is that the shower is rather small, even by Japanese standards. I am 180cm and my head brushed against the ceiling fan if I stood up too straight. Just something to be wary of for any of the taller folks out there.
Also be aware that the accomodation only comes with small towels, rather than a large bath towel. There are plenty of them, but just another thing to know about if you prefer to dry off with a large towel.
If you're looking for a cozy place to stay in the heart of the action of Shibuya, then be sure to check out Kim's place.
