An okay option for the price - the main downside is that checkin is very tight (5pm-11pm) and the host will not let you leave luggage with them beforehand. It’s a small space overall, with very room for your luggage even after checkin.
The host never responded to any of my messages on Airbnb before checkin as well, but the staff was friendly and helpful in person, and on-time at 5pm exactly.
Towel and toiletries are complimentary and the AC is nice during the hot summer days. Bed was clean and comfortable. There’s a common space for resting or snacking as well.
The main plus is that the hostel is in middle of a very busy area with plenty to do. Shimokitazawa has vibrant nightlife via bars and live music as well as tons of thrift shops and antique shopping.
