The apartment is located in the Korea town, close to Higashi-Shinjuku station. It was globally clean. There was a washing machine, but it was not in the apartment, it was in the corridor and common to all the clients. I was with my two children and it was OK, but I think it would be too small for 3 adults or 2 adults with a child. Everytime I had a question, the host answered very quickly.
