I arrived early and the host let me check-in, so I'm really appreciative. She helped me bring in my luggage, explained rules and expectations, pointed out various facilities in the building and gave me the keys to my room. It is small, but it's a good size if you're spending most of your time outside. Easy walking distance to convenience stores and stations and away from noisy traffic.
Great place to stay if you're open and okay to having a private room in a shared multi-floor residence. There were other guests but I believe we were all placed in rooms spaced out from each other so noises were generally just from early risers.
There are rules for the kitchen and the shared fridge but this means everyone's items remain untouched. Coin laundry and dryer are available but make sure you have your own washing detergent. You can also hang out your clothes on the roof - it was extremely nice weather when I hung mine out in the morning and the wind helped everything dry quickly.
The rooms can get stuffy but the window can be opened and the aircon can be used.
The beds are hard, the futons are a bit stuffy and the pillow is rather thin, so it's not recommended if you have sleeping requirements, but sleeping on my back helped.
Would stay here again if I'm in Tokyo for a few nights.
