The house is slightly away from the city centre. It's around 1km from itabashihoncho metro and Jr jujo station. We had a metro pass so we used the metro station. The house is not very close to the main road but sei's instructions were on point and we had no trouble finding it. The place was exceptionally clean. We were 5 of us so we had the 4 bunk beds and the sofa bed. It's a small house but quite comfortable. We had one backpack each so space wasn't an issue. People with larger bags may find it cramped. The pocket wifi was great and very helpful. The house had all necessary amenities like microwave, hair dryer, fridge, basic things like coffee tea sugar and salt. She had also provided shampoo and body wash along with sucheta towels. We didn't use the washing machine so can't really say much about it. All in all I think sei's place is extremely value for money for an expensive City like Tokyo
