Generally the property was excellent and well located, our only problem was with the furniture in the apartment we were allocated.
To be honest it was a bit skanky, the fabric arm chair was not used at all as it was covered in suspected dry unidentifiable human secretions.
The couch / futon is well on its way to a similar point, an update of the furniture is desperately required.
Despite this we enjoyed our time in Tokyo and this property was a good place to stay.
