Our stay was great and I would definitely recommend this place! The apartment was modern and very clean. With 3 adults and 3 large suitcases, space was a little tight, but we only used the space to sleep so it suited us well. The host sent a website ahead of time with all of the information you would need. We would say the walk to the nearest JR lines is a bit far, longer than 10 minutes, but not too bad. We used the JR Yamanote line for almost everything, so it was great to be near that line. We actually preferred to walk to the Otsuka stop instead of Ikebukuro when we could.
