Yoshi was a great host and even invited me to come to a party at his bar. While I couldn't attend, I was grateful for the offer! In regard to the space, it's a great value option, especially for solo travelers. There are signs that explain procedures and where everything is. Just a note, there's a washer (and free detergent powder) but no dryer. You can hang up wet clothes in your room though, and if you absolutely need a dryer, there's a coin laundromat down the street. The place is close to Asagaya station on the Chuo line, which makes it a great location to get anywhere quickly (whether by Chuo or Yamanote). Just be sure to use the rapid or local trains to get to Asagaya, especially in the evenings, since the other limited stop trains usually skip it. It's a straight shot to and from the station, but just be careful not to take the wrong side street.
