i stayed 4 nights with 5 people. The apartment was a bit tight but that was expected. The sofa bed was surprisingly comfortable to sleep in too. The room looked professionally cleaned, didn't find much dust at the curtain bars or the odd corners of the room. The host, Kasa was quick to reply to my messages too. The room is right outside Higashi-Matsubara station, and you can take about 10 minutes ride to Shibuya station or 5 minutes ride to Shimokitazawa station. There was a Lawson right across so it was super conveient too. I would stay here again if I'm travelling with a large group/family of 5. The train is right behind the house so you can hear the train tracks rumbling and announcements at night (not very frequent, i didn't have a big issue with this)
overall wonderful experience staying at this room.
