It has been a pleasure staying at Katsuhiros Appartement. It really felt like a home. It‘s super cozy, has everything you need and more and is super located! Just a 3min walk from shin-Okubo (yamanote line) and around 10-15mins to shinjuku Station.
I hope to stay there again during my next Tokyo trip.
Couldn’t expect more for that Price in this area. Can highly recommend it.
