I 1000% recommend Norimasa’s place. It’s in a hip yet traditional and authentic neighborhood. It’s was super clean and cozy and had some thoughtful touches. Spoons, a hairdryer, a hot water tea maker thing, a clothes line...
Some people in the reviews have complained about the Karaoke place across the street being too noisy. I was there only weekdays so I can’t really speak for peak noise. I heard a few songs, but after a long day of exploring and an earplug I fell asleep no problem.
Norimasa is definitely the best part of the experience. He lives nearby so checking in is easy and it was comforting knowing he was nearby, in case I had any problems.
He’s so warm and welcoming yet respectful of privacy. If I’m back in Tokyo, I’ll definitely stay here again :)
