We booked this place during the winter but the walls were too thin and the cold air could not be kept out. The heater was of no help too despite it being on the highest settings. We had to literally put another layer of walls on the window to keep the cold hair in and it was still too cold.
The stairs up to the beds were steep and old, because it is made of wood it is slippery and dangerous.
The futons and beds smelled mouldy making it hard to sleep, the space was too tight and dark since there were no windows, it was basically a basement.
Do not be fooled by the ‘Asakusa’ title as the place is a 15 minute walk to the nearest station which is 20 minutes away from Asakusa. For its price it is not worth it and you can book a hotel or a better Airbnb near Asakusa.
I do not recommend this place.
