Lovely room designed with modern bunk beds. Out of the 5 hotels we stayed in Japan which 3 were 4.5 stars standard, my 8 years old son actually loved this hotel the most due to the lovely bunk beds design!
The room is not too big but enough to accommodate 4 sleepers comfortably (though limited space for luggage). It has a lovely sofa by the window where you get to see the river and bridge next to the hotel.
Great quality beds, clean room, the staff at the receptions are very helpful and friendly. It's about 12 minutes walk to the Ryogoku Station. Will recommend if you are looking for simple, modern design and doesn't want to break the bank. We stayed here for a night at the end of our holiday before going to Narita Airport to catch our flight back to London.
