Very good Airbnb. The shared part is very nice and invites you to socialise with the other guests. The nearest subway stop is a 10 minute walk. The neighbourhood is very calm and residential (compared to the usual craziness of Tokyo). A convenient store is located just next to the house, very convenient!
Just a practical tip: if you want two separate beds, make sure to specify that if you are staying in the dorm room. The bed is bigger then a single bed, but it's still quite small when you are with 2.
