(Only communicated with host in Japanese) - I believe Kota speaks English well, and room guide is in English in the room.
Kota's place is great for Solo travellers, perfect if you know Tokyo well and just need a place to stay. Very typical 1K style apartment, great for *smaller* people, if you're 6ft+ and used to big houses/apartments, you may find this place cramped. BUT, it's absolutely great for the price.
Location is out of the way, and not near any tourist attractions, but in a nice suburb area in the central circle of Tokyo on the Fukutoshin line. You'll have fun walking around the local area, there's a great Melon-pan place up the street.
I've lived in Tokyo for many years, and Kota's place was just what I needed to visit friends for a few days.
Plenty of fresh towels, shampoo and a washing machine. Lovely greeting message. Superb, would recommend 100%!
