Functional flat located in a very charming residential area. Relatively cold during winter but the AC will fix it in a matter of minutes. Konbinis, a supermarket open 24/7 and lots of decent restaurants are within easy reach. From Hana-Koganei station (also a 3 min walk from the flat), Express trains will take you to Shinjuku station in ~30 min.
Remote workers will find nice coffeeshops around, I highly recommend Hana Cafe Style and Sign Café Very You for power outlets + WiFi, or Hoshino if you require neither.
Kanako and Gianlucca were nice and helpful, they even lent me a bike, which is a great way to discover Kodaira-shi.
One single regret: I cannot recommend renting this place if you’re on a Working Holiday Visa looking for a long-term stay requiring a postal address. K+G didn’t want mail delivered at this exact address, which may seriously compromise your stay in this specific case as this is a necessity regarding matters such as mobile plan / bank / Resident registration. All the rest was great.
