This studio is a great spot for a solo traveler on a budget who has some prior Tokyo experience! The location isn't actually near the Nakano Station, despite having Nakano in the title listing, so be aware of that. The location is still very accessible via Fujimidai Station, so I'd recommend doing some train map tests to see how far you'll be riding on a daily basis. Overall it's pretty easy as the Fukotoshin line usually turns into the Seibu Ikebukuro line so if you're normally hanging in Shibuya/Shinjuku you'll be alright when trying to get back on 1-2 trains.
The studio itself is very quiet and relaxing and the shower/bathroom set up is familiar for westerners and is very clean. The bed is a little bare bones and pretty firm, but overall a very simple and quiet place to sleep at the end of the day as opposed to a crowded hostel or large apartment building. Free wifi is also a nice feature.
Taturo provides a ton of information about how to access the studio from the airport and other info, but can be a little overwhelming so if you already are familiar with getting around Tokyo, stick to your methods and you'll be in great shape.
Lastly, don't be put off by providing your passport photo/other information to the host, it is required by law in Japan as of early 2018.
If you're an easy traveler and the location works for you, this is a great choice! Thanks again Taturo!!!
