Yuki's appartment is very cute and full of conforts. It is greatly located, just few mins by foot from Ebisu station where it is possible to use the JR trains (very helpful if you have a JR pass). Ebisu is a lively quarter full of restaurants but still quiet if you want to stay away from the chaos of the busy Tokyo. Nevertheless it is just 2 stations from Shibuya. Yuki is a great host! She answers in the span of 5 mins and is always available to help. She made our laundry in her flat (which is at the 7th floor of the same building) and brought it clean and dry to us the day after. She also provided a portable wi fi for free! We stayed 4 nights and the 2nd day they came to clean the flat and change the towels. The cats are adorable but they only come if you ask Yuki, otherwise you won't see them.
Only one thing: the sofa - bed is big enough for one person, the second person would sleep on a tatami on the floor but this is quiet common in Japan!
