The front door was difficult to find because it was behind another building, but it was easy to get to by metro, and the rules were well explained.
The public spaces were cleaned everyday and they even have supplies in the livingroom to clean your own room if needed.
When a friend came over for 1 night they didn't fuss which was great!
They always replied quick, sometimes within a minute, and responded to all my inquiries.
I stayed for 3 weeks and it was totally doable.
If you don't mind being 30minute walk/ 8+6min walk+metro ride away from the closest JR trainstation (ikebukuro) it is beyond worth the price/accomodation!
I could even go clubbing in Shinjuku and get back without issues with either the last of first trains.
great recommendation!
