Second time staying in Ryogoku and firstly, the area is brilliant. Really quiet and tranquil, which is perfect after spending the day in busy areas like Shibuya and Shinjuku. The local station (~5 min walk) is the JR Chuo line and is easy to get to all the places you need to see. I’ll be honest, I had relatively low expectations of this hotel based on the price per night, but wow! It’s amazing. The staff are so friendly and super accommodating to foreigners, it’s really clean. Rooms are cleaned at request, and if you opt not to - they will provide you with fresh towels and a robe in a bag placed outside of your door with zero disturbance (for days where you arrive home pretty late at night!). the bedroom is equipped with a smart TV that allows streaming from your mobile device. I didn’t get to try the onsen facilities, but have heard they are lovely. Didn’t get to try the breakfast either so can’t comment on that.
