Sato answer the messages quickly. Walkable distance from higashi-ikebukoro station and closed to sunshine city. If you come from Otsuka station(JR Yamanote Line), you have to walk up hill a little bit. Or you can use tram from ostuka station to reduce half of the distance. The apartment is big enough for 6 people. Its very clean and basic amenities are prepared for you( towels, shampoo, etc.) When we enter the apartment, we had a problem with the light, Sato responded our message quickly and send someone to checked it out. At the check out date, Sato also let us leave the luggages in the apartment which is very helpful. Thanks alot!
