Apartment is per host says - 3 mins to Komagome station, and is on the Yamanote line, so access to Tokyo, Shibuya and Shinjuku stations are direct and easy. Convenience stores are just a walk away from the apartment, and there are three bakeries nearby (one of which is in the Komagome station itself). Best part of the stay was being close to Rikugien Garden, which we had a great morning taking in the autumn colours.
Apartment is equipped with amenities like toothbrush, facial wash and cotton buds, which were all useful during our stay. The water pressure was good and the water heated up real quick.
The only downside probably is that the room is rather small for 3 pax, I would say it is comfortable for 2 pax with lugguge, since we had very little space to walk within the room and had to keep taking turns to open our lugguge. One set of the power socket wasn't working too well during our stay.
