The location is amazing. Dedicated floor leading to the 7th floor elevator. Private.
It is right outside of JR Ryogoku Station.
Ten adults can stay comfortably if you don't mind sleeping 2 to a bed.
Two showers and two toilets are great to have, but one of the showers maybe too small and the water pressure and heat couldn't be used at the same time. If you don't mind taking turns, it was fine. But having two bidet toilets are wonderful!
Wished there was a big mirror by the sink. There is no kitchen, but if you don't eat much in the room, it was perfectly fine. The microwave and hot pot was more than enough for us, there is a hot plate and lots of utensils, cups, plates, etc.
Nice closet space and veranda if you want to do laundry, the washing machine is really tiny, but convenient.
Overall, great place to stay and highly recommended.
