Sho was a great host. He checked up on us if everything was good with our stay 1 week in. Its a cute little Apartment with a great bathroom and shower. The place was very clean upon arrival and nicely prepared. It's right in the middle between Shinjuku station and Tokyo station and it's very easy to get there using the marunouchi line.
-Note there is only little to no space under the bed to put any luggage. It might get a little cramped if 2 guests arrive with 2 luggages each.
I greatly recommend this place for solo travelers or couples who are staying for a short duration(~1 week).
