I was in a pinch when I booked Tomoko's place because I had experienced a same day cancellation of my previous stay due to changes in Japanese law. Tomoko responded really quickly and with informative responses. She was very flexible and accommodating which helped me a lot. Because it was such a last minute reservation, I didn't get that much time to look deeply into the place so I was pleasantly surprised by the place. the tatami floors and sliding doors are an interesting experience. Note, the bed is a double futon on the floor. as a person who likes firm beds, it was comfortable for me but for many, I know it won't work. the room is quite small, only suitable for one comfortably. the home, despite having other guests, was quiet and felt private. Tomoko also arranged a taxi for me and made breakfast on the final day. it made leaving super simple. about location, it's in a quiet area but the train runs nearby. the plus side is that you're 1 min from the station and surrounding 24h convenience stores. the downside is that (1) you hear the train running by from the room (although it's not loud), (2) the station is part of the Tokyo ikegami line and takes a few transfers to get to popular destinations in tokyo and (3) it takes about 40min to get the popular areas in Tokyo during downtime and up to 1h during rush hour (in fact, avoid traveling at all during peak hours) . if you need to travel to haneda airport though, it's great. very close by. overall, I'd stay again and would recommend to others (who aren't too focused on being in central Tokyo) mainly due to the place being comfortable and the host being great.
***also, special note for people with accessibility needs, this place is not the place for you. steep, curving stairs only.
