I think this place is really great! Kazutaka and Megumi is very responsive to our messages.
And the location is very near to Mikawashima Station. From here we can arrive from Narita directly. And go directly to Nippori Station, Ueno Station and Tokyo Station. And then change train to Disneyland, Shibuya, Harajuku, etc..
The place is also very nice. It is so comfortable and all of us enjoy it so much... I am really recommended it.
