Stayed at Vegeta House during Christmas 2022. Very clean and cozy. Pretty small bathroom and shower. Internet is insanely fast.
The apartment is not every far from Hatagaya station. You can find it on GoogMaps if you can read Japanese. Otherwise Mitsuko is more then happy to help you locate it. Relative to the rest of Tokyo, its fairly close to Shinjuku and Shibuya. It’s slightly out of the main metro circle so you sometimes have to get off at Shinjuku to switch to the New Keio Line (NOT the same as the normal Keio Line) to get to Hatagaya. The suburb has very quiet working class vibes. You walk past a number of small bars and restaurants that come alive at night to get to the apartment.
Speaking of Mitsuko, she is a very friendly and responsive host. We were working from her AirBnb and we needed an extension power board and she was able to provide us with an extra one in a few hours. A+
