The hosts at Grapehouse Koenji were incredibly helpful and welcoming. The space was very clean and comfortable, and the other guests that I met there were also all very nice! It's all a shared space, but you're free to come and go throughout the day for personal sightseeing and such. The location is just a short walk away from the train station, which has access to one of the main lines for places like Tokyo, Shibuya, Shinjuku, and other popular areas.
I loved my stay here, and would absolutely consider booking again the next time I visit the Tokyo area!
