The place is exactly what is described. John was easy to communicate, he would reply promptly. There are some parts of the house that needs to be improved. Bathroom is good but a bit rusty in some parts.
Location is good because it is near Shinjuku. However, train is not so reliable.
Nearest train station is a subway. If you're going to touristy places, this subway line would be a challenge as there are not enough line that connects directly to it. You would have to transfer a lot or just walk to Shin-Okubo or Shinjuku.
Shin-Okubo station (Yamanote line) is a 10-15min walk. Shinjuku Station (15min walk)
It is said in the description that wifi is included, however we weren't able to use it because the previous guest used up all the data. Good thing we rented out our own internet!! We should've been given a discount. Fyi!
The appliances were labeled with "read the manual" but there was no manual at all in the place.
Overall it's a good place to sleep but you should set your expectations.
