This apartment is unique in that it has two levels with beds on each floor. It's perfect for two travelers who may not want to share a bed (friends, siblings, etc.) and offers some privacy for both. If you know anything about Japan, you know that hotel rooms and apartments are tiny... This residence is probably larger than anything you may get for the same price in a comparable area, a fantastic residential neighborhood with two embassies nearby and within walking distance to three train stations.
The drawback, as some reviewers have noted, is the long outdoor staircase which leads to the residence, about 40 steps in total. Taxis will not be able to come directly to the door but only to the street above the staircase. HOWEVER, the host will help you with your bags! Make sure you contact the host beforehand if you have heavy luggage and they will help you bring your bags down and up. This residence is not recommended for anyone who may have issues with walking or a have a bad back, as there are small steps inside the apartment as well, but for those who can navigate staircases, you will be rewarded with a beautiful clean space in a great neighborhood.
The apartment description concentrates on Shibuya station, but that is actually the farthest station of the three, about 20 min walk. Much closer, at about 12 min walk, are the Yoyogi Koen Station (Chiyoda Line) and Yoyogi Hachiman Station (Odakyu Line). These two, especially Yoyogi Koen Station, are super convenient to get around the city, much more so than Shibuya in my opinion. The street leading to these two stations are lined with great stores and restaurants. Shibuya Station and the surrounding area are undergoing major construction until 2020 and is extremely confusing right now which is another reason I highly recommend the two other stations.
