Great location. I was concerned that it might be too far from attractions or too close to the train but it’s really great. The train is close but quiet and it’s a short walk to the station. Shinjuku is a quick train ride away. Koenji is more of a neighborhood and less packed with tourists so nice to be away from the hectic crowds. There is a great ramen place (red awning) just toward the station and the owner was so nice. The restaurant is small so we had the food delivered to the house. Also saw a vegan restaurant though we didn’t try it. The house has a lot of stuff for babies and small kids, toys, potty seat, high chairs etc. Highly recommend Emi’s place!
