I've stay here for one month. Mr. Kenichi is very friendly! He respond really quick usually (less than one day), and his informations are really helpful. He had the bar downstairs, you can have a nice chilling night there. Their food are delicious! Mr. Hiroki speak fluent English and very friendly too!
The accommodation is really near from public transport:
1. JR suidobashi 5mins
2. Subway Mita line suidobashi station 5mins
3. Subway kasuga station 5mins
Besides, there is a super cheap supermarket just around the corner name donki! 5mins walk to Tokyo dome and you will find a lot of nice food there and along the street from suidobashi station. There are 3 convenient store nearby (Lawson's and 7-11)
The equipment that he provide is really convenient! Good wifi, Towel from muji, ion hair dryer, 記憶枕， water machine in the living room, heater in the shower room, kitchen equipment included stove and microwave! They had washing machine too! I love the art piece in the room, the convenient electric cables, bed light~
At last, I said truly that I highly recommend this place, it is really convenient to stay! I hope you enjoy ur stay as much as i does.
