There is no bad thing I can say about staying at Yuka's place. The apartment was clean, spacious, there was everything one would need for convinient life in Tokyo and the Wi-Fi was very fast. Another thing is that the apartment is close to supermarkets and a bus and train stations. One can easily get quickly to Shibuya or Shinjuku from there. Yuka's hospitality is another big advantage. The staff replied on my messages really quickly so any problem could be solved immediately.
