Very clean and comfortable! You can see that they come and clean the whole place everyday in the morning.
There's kitchens for you to cook and also microwaves. There's coin washing machine, clothes dryer and place to hang your clothes too on the rooftop.
It's 10min walk to Asakusa station, and the night views around Azuma Bridge is wonderful. Tokyo Sky Tree is visible from the rooftop of the guest house (*ﾟ∀ﾟ)
