My husband and I stayed with our son for 4 nights. We were all very comfortable and felt right at home.
We had a little difficulty finding the key (it was inside the lock mechanism). I had messaged the owner,who responded very quickly.
The location is quite handy to the train station, but still not noisy.
My only suggestion would be some more cooking equipment, perhaps an electric frypan and a toaster.
We would certainly stay here should we ever visit Tokyo again.
Thanks to the hosts for their quick responses and lovely accommodation.
