The appartment has very good location and good restaurants near there. Satoru and kazue are kind and helpfull all the time.
The negatives things are that the apparment it's small for 4 but it's OK if u only sleep in there. The pocket wifi it's only for 10 MB and it's works for a few days but i must to recognize that satoru gave us a new one and was great.
Anyway it's a good place in tokyo!
