It's close to Tokyo university and 2 mins walk to subway station, 11 mins walk to JR station （It's very complicated to find the route to the place when I arrived Nippori at midnight. It's better to arrive in sendagi subway station.)
The host is super nice and the place is overwhelming, big, clean, quite and a big dark bedroom. You own the whole house with two floors and could live in at least 6 people.
It's not in a travel district and all the restaurant close before 11 pm, If you don't mind. I highly recommend it to the tourists.
