We enjoyed staying in Ochiai, the neighborhood was nice and quiet. Wisterias place was clean and well planned. We had no issues staying there even though we were 4 people with a considerable amount of luggage. Going into and round central Tokyo with subway was no issue during the day but as the subway stops running around midnight (even on weekends) it's not ideal if you're interested in nightlife, as taxi fares are quite expensive.
But would definitely recommend a friend staying there!
