I love my stay at Tasu Toco. It is literally 1 minute from the Nishi-Kochijoji train station. The apartment is beautifully designed. Modern interior with concrete walls marrying Japanese traditional design with tatami mats and antique cabinetry. I found it very stylish and cosy and i loved coming home to it from a long day exploring Tokyo. Some nights I can hear Jazz music coming from the bars below which i loved.
Nishi-Kochijoji is a lovely and quaint neighbourhood with cute cafes, bars, restaurants and vintage clothing stores. The supermarket by the staion is fantastic for stocking up everything from wine, great ready-made food, fresh seafood, meats fruits, dry goods and much much more!
One station away is Inokashira Park which would be beautiful in Spring, Summer and Autumn. It's about a 20mins walk away or a few minutes by train. I chose to walk as I loved exploring the various neighbourhoods of Tokyo. Another 15 mins or so away on foot is Mitaka which is wgere you'll find the Gibli Museum. Book your tickets in advance if you wish to go as they don't sell it at the door.
If you are a light sleeper, you'll need to keep in mind is that you are right by the train station. You will hear trains passing though I never found it intrusive.
Overall a very quaint area to stay and explore. My host Ko-san was very accommodating and was very quick to response with tips for a variety of places to eat and explore.
