I loved my stay here and would 10/10 recommend!
It's perfect for a solo traveller in the quiet neighbourhood of Shimokitazawa. It's a few minutes walk away from two lines that makes it very easy to access Shinjuku and Shibuya and about 10 minutes walk to the busier side of Shimo-kitazawa. It is also quiet so you can relax and sleep at night which I enjoy because Tokyo's hustle and bustle is overwhelming for me.
The place is the perfect size for myself (a solo traveller). It had the best bed during my trip in Asia so I was able to have great sleep! The bathroom is also very typical Japanese and I was super happy to have a bathtub. One additional thing is I had a request for Kuniaki-san and he was super responsive and helpful in fulfilling that request and even went above and beyond so I am very grateful to him. Would stay here again the next time I'm in Tokyo! Thank you!
