Tsuyoshi’s place was very comfortable with a lot of sun and wind coming through the window. The room is not big but livable. I didn’t use the bed on the loft as it wasn’t easy access so it ended up being a storage area for me because there’s no closet to store your clothes, shoes or your suitcase. The kitchen is small so if you love to cook, it might not be your place but you’re so in downtown that you can order anything from ubereats. The house is walking distance to shinjuku, Yoyogi, sangubashi and minami Shinjuku so it’s really convenient however there’s not much of cafes with taste in the neighborhood. I used Life Son and Dimilight Espresso but that was about it.... in terms of noise I wouldn’t recommend it to anyone who gets annoyed about outside noise.
You can hear people upstairs quite well, mainly kids walking and running around. There is an office on the first floor and often times the staff stay until late at night discussing their work plans etc. I usually had my window open so I could hear every conversation.....and they were there until 11pm ish which sometimes bothered me. But it was nice to hear birds chirping in the morning! In terms of cleanness, the room wasn’t really clean when I first got there so I had them come in and clean it again. Other than that, I really enjoyed staying at Tsuyoshi’s and would stay there again for my next stay in Tokyo.
