Amazing place. About 4 minute walk from Yoyogi West (MAIN) Exit and you would pass by Starbucks, local restaurants/cafes, convenient stores and a great supermarket on your way home. Walkable from Shinjuku station (around 15mins) as well. We are a family of 6 adults and we are able to fit comfortably. It can fit maybe 2 more females/children. It is true that the stairs to the attic is a bit steep (and you can't stand in the attic - only crawl) so it would be better if young adults stay in the attic. There are two toilets and one bath which are separated from each other so it's relatively easy to use restrooms even if we are large in number. There is an AMAZING massage chair you can use after a long day of walking. Aircon and heater works well. Mobile wifi works well. TV has Netflix. Tokyo is an amazing place but it's even made more amazing when you have a home away from home, which was provided by this airbnb listing. Only comment I have is I wish check out time be a little bit later (around 12noon, instead of 10AM) - apart from that, we are very happy with the place. You have nothing to worry about!
