Absolutely loved this place. It's right in the Shin-Ōkubo area, not far away from the JR Station and even closer to the subway station. Also it's in a walkable distance to Kabukicho (a few blocks and you're in the rustle and bustle of Tokyo's nightlife capital).
Min & Haru were super friendly and had no issue with my delayed arrival from Narita. The tatani room itself was spacious and cozy, there also was an air conditioner. And the roof! Great for late-night snacking and chilling. Overal I had really good experience and can't recommend it enough!
