Bunkyo is a good value for the money. We stayed for 3 nights here while in Tokyo. It's close to a few markets (7 Eleven, Lawson, Family Mart) which is really helpful and convenient and it's 5min walk to Hakusan train station.
Host let us keep our bags in the lobby before checkout
There's fast, free WiFi here
They have a shared fridge, hot water kettle, and microwave.
There is a washer here for 200yen, no dryer
This is a shared space with a handful of individual bedrooms each with their own lock with code on the door. You share 1 shower stall that did come with shampoo and body wash. You also share separate male and female bathrooms.
Our stay met our needs. The beds we're comfortable, not hard in my opinion. The AC in the room worked great and you can also fully open your window (which I recommend if you are drying laundry). Our only complaint was the bed sheets did not feel very clean and the shower towels given to us were microfiber (which don't absorb). The towels began to smell after a few days and washing did not help. We let our host know about these things after our stay so hopefully have fixed the issue!
If you want a no frills stay in Tokyo to just sleep for a few nights with the necessities, I would recommend this place, it's a good value! If you can pay more, you will obviously get more!
