We loved our stay at Jenny’s place. The room is spacious ( esp for Tokyo) and super clean. The tatami mats were totally comfortable and we slept great. Her place is on a quiet street very close to 7-11, laundry , lots of delicious places to eat ( def get her recommendations) and the subway. One note - the subway stop closest to her is 1 stop outside of the Tokyo metro which is no problem but you may want to consider that if purchasing a tourist metro pass.
Highly recommend staying here - we had a great stay!
