This is a perfect room for a solo traveller to Tokyo! It is comfortable, clean and just as described. The house is located down a quiet street, just back from the hustle and bustle of Korea-town. There's a JR train station not more than 5 minutes away which can take you into Shinjuku, Shibuya, Tokyo, Ueno, Harajuku and more, and Shinjuku is about 15 minutes walk for heaps of restaurants, arcades and shops.
The host's communication was excellent and self check-in was really easy. I was there in winter and its a bit chilly, thankfully there's heating in the room which keeps you nice and cosy. The bathroom is shared, and has everything you need.
Highly recommend this place for a comfortable and convenient base in Tokyo :)
